What Makes Specialty Gases So Special?

When perusing the specialty gas market, you will likely quickly notice a variation in prices. This may seem surprising at first, as those less familiar with the market and custom calibration gas standards may believe that the gases themselves lack variation. In fact, the specialty gas market itself only has two separate categories. These include pure gases and gas mixtures.

It may seem odd to some consumers that natural gases have such shifting prices, as it may seem to be a product that lacks change. However, there is a very specific process involved in extracting gases from the atmosphere, and then separating them. The process involves a good amount of energy and is rather sophisticated, which accounts for why the prices can jump at times. As energy prices climb, so too will the cost of extracting gases from the atmosphere. Therefore, specialty gas providers will need to charge more.

With that being said, the market has become incredibly competitive, which means that companies will sometimes lower their prices in order to outbid a competitor. However, it’s important to remember that specialty gases themselves are complex products, and there can be much more to them than what may initially meet the eye. For example, extremely pure gases have a range of applications. They can be used in the creation of pharmaceuticals medicines, as well as electronics. Even the aeronautics industry can rely upon specialty gases. If you as a consumer are seeking out specialty gases, then you understand the demand for the product, and why it is so valuable. Nonetheless, let’s explore further why specialty gases are really so valuable; and indeed so special.

How Are Specialty Gases Produced?

Above, we explored the technicalities that go into extracting specialty gases. Specialty gases are sometimes not made to be widely produced. Rather, they are meant to be unique products made for one particular usage, and perhaps only for a short time. This is why custom calibration gas standards can often differ widely from specialty gas to specialty gas. Specialty gases often require much more engineering compared to the widely produced industrial gases, and can sometimes take longer to produce. They’re rather complex and often have extremely high purity levels. It should come as no surprise that the custom calibration gas standards of these concoctions can be extremely specific and exacting. Even the manner in which these gases are packaged must be tailored to their needs.

How Are Specialty Gases Packaged?

Usually, specialty gases are packaged in cylinders, as they are not being transported in vast quantities. Specialty gas products often must be packaged in aluminum alloy cylinders, as opposed to the typical steel cylinders utilized for less specialized gases. It’s extremely important that the gases remain uncontaminated. The strict containment procedures related to these gases also relate to their fluctuating values. The gases must be carefully maintained as they are transported in order to ensure that their integrities are protected. These procedures are followed with the buyers in mind; as they are likely paying a premium, they should receive the premium product in return.

How Is Quality Control Assured?

Returning to the idea of integrity, it may be difficult to understand how these specialty gases are regulated, especially considering their uniqueness. Custom calibration gas standards do of course play into these regulation procedures. Specialty gases are carefully inspected by experts and are often released with a certificate to consumers. These certificates attest to what the gases contain, and verify that they are being sold as they should be. Specialty gases must be analyzed over a more extended period of time than more standard gases, as they have less to be compared to. Again, this accounts for the longer production times they require.

As with any specialty products, specialty gases can be difficult to create and maintain. However, this should account for how much they cost, as well as the competitiveness of the specialty gas market. These products are essentially being tailor-made for consumers, and will, therefore, yield very different results compared to standard gases you may be familiar with. Therefore, you should be prepared for accompanying pricing variations.

7 Must-Know Tips on Gas Cylinder Safety

Gas mixtures and pure gases are the two categories that make up the specialty gas market. Liquid Petroleum Gas (LPG) is among the most efficient and preferred energy source in many homes today. Specialty gas suppliers make sure that the cylinders are strong to keep damage at bay and are safe for homes. Leaks can at times occur in pipe connections, gas regulators, and other gas handling equipment. Here are gas cylinder safety tips that will help avoid danger.


1. Gas Cylinder Storage


Whether in use or not, cylinders need to be always kept at a safe place. As a rule, they should at all times be in an area that is properly ventilated. Exposing your cylinder to direct sunlight or other heat sources is a big no-no. You need to have it far from electrical power sockets and inflammable substances.


An outdoor cylinder needs to be in a cabinet that has a wired net beneath. This means that in case of any form of leakage, the gas will simply escape in the surrounding air.


2. Gas Cylinder Positioning


Always keep your gas cylinder on a level and firm surface in a vertical position. The gas regulator side should face upward whereas the cylinder’s bottom should touch the level surface. Refrain from placing the cylinder horizontally or even rolling it when in need of more pressure. Gas handling equipment such as the cylinder’s valve and gas regulator have to be within reach as well.


3. Gas Leakage


The smell of gas in your living space means that there is leakage. Lighting a lighter is not a good way of confirming this as it can easily result in an explosion and fire. Turning off the gas regulator is the first thing to do anytime you suspect leakage. A water and soap solution will help you confirm leakage by the appearance of bubbles in the leaking area. The solution will simply flow if there is no leakage whatsoever.


Never turn off or on electrical appliances at such a time. Open all doors and windows as this allows any leaked gas to diffuse in the air. Placing the gas cylinder in a properly ventilated area will also be a step in the right direction. Should the leakage persist, seek assistance from your specialty gas supplier in order to help prevent danger. Your supplier most likely has the necessary gas handling equipment and know-how needed to efficiently stop leakages.


4. Gas Cylinder Replacement


After your gas cylinder runs empty, there will be no other option but to go get another one. Getting a replacement calls for due diligence and sourcing from an authorized specialty gas supplier is the best thing to do. When getting a new one, always go for a company sealed and filled gas cylinder instead of one that’s manually refilled. Keep in mind that cylinders from authorized dealers are the best because they meet the required industry standards. On the flip side, unauthorized sellers will most likely sell you a cylinder that is substandard.


5. Maintenance


Whether LPG or natural gas cylinders, proper maintenance is something that you cannot afford overlooking. In most cases, accidents are the result of malfunctioning gas handling equipment and this calls for regular checkups. Checking for rust, dents, and other types of damage will help you know whenever the cylinder is in bad shape. Retest and manufacturing dates usually indicated at the cylinder’s bottom will help you determine its validity. Don’t forget that cylinder maintenance is a job that shouldn’t fall in the hands of incompetent persons.


6. Gas Cylinder Transportation


Most people are in the habit of rolling cylinders when moving it from one area to another. This is bad practice as cylinders aren’t designed in a manner that allows rolling and/or dropping. Remember that the cylinder’s valve must always face upwards.


7. Turn Off When Not Using


Turning off the regulator or valve after usage should be part of your lifestyle. This is especially so when leaving your home for extended periods of time. This is a simple tip that will go a long way in the prevention of unexpected accidents.


Final Words


Knowing how to stay safe when using gas cylinders is always a wise decision. With the above tips, you’ve all it takes to keep accidents at bay.

How to Select the Best Specialty Gas Provider

Finding a specialty gas provider is a very important task. With many options out there, it can be difficult to make the right choice. But it’s possible to find one that supports your needs. Here’s how to select the best specialty gas regulator.

Examine Safety Protocol

Dealing with specialty gases requires superior safety. It’s essential that any specialty gas supplier you’re considering strives to give you a safe product. Visit their website or contact them to learn about their safety procedures and how they mix their gasses. If you find out the supplier is using unsafe tactics, don’t obtain specialty gases from them.

Consider Custom Calibration Gas Needs

The needs for your business might not be the same as another company’s needs. You need to find a supplier that provides custom calibration gases to fit your requirements. A gas supplier should be able to have the expertise and knowledge to adjust products to what your business is looking for. Ask if they consistently measure and confirm the value of the specialty gas when manufactured. Any supplier should be meeting the best industry standards for custom calibration gas.

Explore Multiple Services

It saves time to find a company that can provide multiple services, rather than having to find different companies for different services. See if the company you’re considering also provides high purity gas equipment. Do they also assist you with a delivery system? Do they have reliable technical support? These extra services will make a difference for your business.

Learn About On-Site Laboratories

Sometimes, you need a service to be done with a quick turnaround. A gas supplier that has an on-site laboratory has the capabilities to deliver you specialty gases as soon as possible. Another added bonus with choosing a company with an on-site laboratory is that the supplier is more able to develop gases that are custom to your specific goals.

Ask About Pricing

Avoid companies that seem to be concealing their fees or add a lot of additional charges. If they’re that focused on your money, they’re probably not that focused on providing you the best service. Make sure they’re upfront about their pricing and that their pricing is in line with industry standards. Don’t choose a supplier based on costs alone.

Assess Customer Service

It’s important the company cares about providing good customer service. If they end up providing bad service, you’ll be looking for a gas provider all over again.

Finding a good specialty gas regulator is more important than ever. Technavio’s market research analyst has predicted that the global specialty gases market will grow at a CAGR of more than 6% between 2017 and 2021. Determining if a company fits the guidelines listed here will help you find the right gas provider.


Factors That Determine the Expiry Date of Specialty Calibration Gases

You can’t eat food that has expired. So why would you use expired calibration gas? Calibration gas is crucial in ensuring that gas level monitoring equipment performs as it should. Industry custom calibration gas standards recommend the use of non-expired gas. This article highlights the importance of monitoring the shelf life of calibration gas before using it.

What’s The Purpose Of Calibration Gas?

You will always need calibration gas to perform any calibration or bump test. Calibration gases correspond to set amounts of the kind of gas that you’ll test. This gas is housed in a bottled compartment that exposes the calibration gas to the gas sensors.

If you use calibration gas that has reached its expiry date, the chances are high that your calibration will not show a proper diagnosis of the gas that you’re monitoring.

Here are the factors that determine the expiry of your calibration gas:

Shelf Life

Each bottle of calibration gas has an expiry date. The industry’s custom calibration gas standards need you to use non-expired gas. This expiration date gets determined by the shelf life of the calibration gas.

As time goes by, the calibration gas in the bottle may disappear. Reactions with other chemicals, changes in the environment, and time passed may cause the decline of the quality and amount of calibration gas within your cylinder.

Calibration Gas Concentration

If the concentration of the reactive gases in your cylinder is high, in some instances, these reactive gases can be certified to serve for a long time. But this wouldn’t be the case if the concentration was low. The low concentration of reactive gases experiences a fast decline in gas volume because of micro-reactions that may occur within your gas cylinders.

That is the reason why the high concentrations of reactive calibration gases last for longer and thus have longer shelf lives.

The Reactive or Non-Reactive Nature of the Gas

Reactive gases have some level of instability, while reactive gases have more stability under many conditions. Reactive gases are also not affected by moisture or most environmental factors. As a result, non-reactive gases last for longer than reactive gases.

Examples of non-reactive calibration gases include nitrogen, methane, hydrogen, pentane, carbon dioxide, propane, alkene and alkane hydrocarbons, and hexane. These non-reactive gases are more stable, with shelf lives of about three years.

Examples of reactive gases include chlorine, hydrogen sulfide, nitrogen dioxide, sulfur dioxide, nitric oxide, and ammonia, among others. These reactive calibration gases have short shelf lives of about a year or less because they often experience a decrease in concentration.

Type of Gas Cylinder

Reactive calibration gases are often stored in aluminum gas cylinders and must be treated with care to reduce reactions that will shorten their lifespan. The internal surface of your calibration gas cylinder should have smooth walls to mitigate the results within the bottle. Rough interior walls have little dents that can hide contamination, which will cause reactions that will diminish the volume of the reactive gases. As you buy, ensure the cylinders you get to meet the custom calibration gas standards quality.

Gas Cylinder Size

The quality and size of a gas cylinder both matter a great deal. Large volume and high-quality cylinders often allow the bottling of gases that have a longer shelf life than those in small and low-quality cylinders. As such, follow these industry’s custom calibration gas standards when buying your cylinders.

Custom calibration gases are essential in performing bump tests. They need to be of top quality to improve your diagnosis of the test gas. They also need to last for a long time to serve your needs. The shelf life of calibration gases relies on various factors, which include gas cylinder size and quality, gas concentration, and the reactive or non-reactive nature of the gas.

The specialty gas market across the world is expected to exceed $14 billion by 2026. If you’re a specialty gas supplier in this market, then adhere to the custom calibration gas standards and use the tips above to prolong the shelf life of your calibration gases.

Understanding Calibration Gases And How To Use Them Correctly

If you’re working with any type of gas, especially in confined areas, a gas detector is crucial. Without proper detection, workers could be put at risk of becoming ill or injured due to exposure to harmful gases. However, in order for a detector to serve its intended purpose, it must first be correctly calibrated.

What Are Calibration Gases?

Calibration gases are used to calibrate the gas detectors to ensure they can function properly. The only way to know for certain that a detector is working is by testing it with a known calibration gas, thereby confirming that the detector is showing accurate readings. This test will also determine if the alarms are working properly on the device or if they need to be looked at and adjusted.

What Are Specialty Gases?

Specialty gas represents special blends of gases that may be rare or have ultra-high purity. Many industries make use of these gases, so having detectors calibrated to show leaks is crucial. This type of gas can be purchased from calibration gas distributors, though it’s important you know the exact combination before ordering. Depending on the size of the calibration gas cylinders and the type of gas needed, products can range anywhere from $100 to $3,000. For standard jobs, however, you usually won’t be looking near the high end of the spectrum.

When To Use Calibration Gases

The International Safety Equipment Association (ISEA) advises testing frequently in areas where conditions could inhibit detector performance. The ISEA provides for less frequent testing under specific conditions, though all testing should be conducted on a 30-day basis.

While there is no hard rule as to when you should carry out device calibration specifically, OSHA provides some practices that are helpful to follow.


    • bump test or full calibration should be conducted every day before using a portable direct read monitor.


    • A full calibration must be conducted in the event that a monitor fails any bump test.


  • All calibrations must be conducted more frequently if the environment has the potential to affect detection performance.

If you have any doubts, always go ahead and conduct a full calibration. By doing this you can confirm the concentration, the accuracy, and the alarm functions.

Quality Gas

When it comes to calibrating, the process is only as accurate as the specialty gasses you use. This makes purchasing any specialty gases, or standard calibration gases, from a reputable source all the more important. Always ask your supplier if they can provide a certificate of verified analysis for each cylinder you receive. This helps you get track of the quality, and have a reference should the gas prove to be unusable.

It’s also important to always check the dates of cylinders to make sure the gas is still usable. Because the concentrations are only stable for a short amount of time, gasses that are past their dates should never be used for calibration.


Testing Tips


    • Always zero your device in clean air.


    • Calibrate every day before use.


    • Fully calibrate detectors every 30 days.


    • Verify sensor information with the data on the cylinder to ensure accuracy.


  • Always use correct fittings and regulators as the incorrect flow can corrupt readings.


Gas detectors can save lives, but only when they are properly calibrated. Don’t take any chances, invest in specialty gases from trusted suppliers, be sure and follow all instructional guidelines, and never cut corners. Above all else, always double-check your readings to ensure complete and total accuracy.

3 Factors to Consider When Selecting the Perfect Regulator for Your Calibration Gas

Ultra-pure specialty gases have purity of at least 99.995% or above. Some of them are specialty gases mainly used in industrial applications. Some of the specialty gases include the environmental gas standards used to check for compliance to safety and regulatory standards.

Environmental gas standards have to first be assessed by advanced computer modeling for possible phase problems before any manufacture of environmental gas standards. After the assessment, the manufacturer does a component compatibility assessment based on the mixture of the required specialty gas. Thereafter, the cylinders to be used undergo conditioning and a proprietary cylinder passivation process depending on the specialty gas that is ordered.

Finally, the environmental gas standards are accurately blended to specifications, and they also undergo analyses meant to confirm whether the specialty gas blends are in agreement with the analyzed values and the required specialty gas product specifications.

This article highlights the importance of a regulator in influencing the performance of your specialty gas in environmental gas calibration standards.

Why is the regulator an essential component for your gas cylinders?

The performance of your specialty gas in assessments involving environmental gas calibration standards largely depends on how well the blend agrees with the requested specifications. But other minor factors such as the kind of regulator used may affect this performance.

Using the ideal regulator is important in getting the best performance from your gas meter. Wrong regulators can bog down your pump and cause inaccuracies in readings after the calibration process, or they may even be totally incompatible with the gas cylinder.

When making considerations to purchase any specialty gas you should consider three regulator-related variables:

1. Flow Rate

All gas meters have recommended flow rates for bump testing and calibration. The recommended rates often lie between 0.5 and 1.0 on the LPM range. These rates are always found on the gas detector manual. The use of gas regulators with an excessively high flow rate wastes gas and floods the sensors.

On the other hand, a regulator with a significantly low flow rate under-supplies gas to the sensing equipment while also straining the pump. The use of pumped meters with a demand flow regulator makes sure that the meters only get the supply of gas that is needed. The demand flow regulators differ from the preset flow regulators by virtue of the fact that they rely on the pump draw to allow the release of the gas. This ensures that the sensors receive the exact amount of gas provided by the pump. These regulators are thus the best in supplying gas to your sensors.

2. Reactiveness

Some reactive gases such as Phosphine (PH3), Hydrogen Chloride (HCL) and Ammonia (NH3) can corrode the interiors of standard gas regulators. As such, gas cylinders containing such reactive gases require regulators with thick internal coating of stainless steel. In addition, highly reactive gases tend to leave residues on the interiors of the regulators, and it’s thus recommendable to use a different gas regulator for each of these gases instead of sharing them among cylinders containing different reactive gases.

3. Threading

Regulator threading is an important consideration in regulator selection. Calibration cylinders often have two types of threading systems. The small 34L cylinders have threads on their exterior, whereas; the large 103L Aluminum and Steel cylinders have internal threading. A gas regulator with internal threads can’t simply suit a gas cylinder with internal threads, and vice-versa. Conversion adaptors are unavailable and if you experience incompatibility in your set-up, then the only option that you have is to replace the gas cylinder or the regulator.

Luckily, the identification of a regulator’s threading is simple. 58L and 34L reusable cylinders always use C-10 regulators with male threading. The 34L steel gas cylinders use the CCA-600 regulators with female threading.

By keeping in mind the reactive nature of the gas, the flow rate of the regulator and the threading of the regulator, you can avoid costly mistakes when buying and trying to match the threading on your calibration gas cylinders and regulators. Failure to select the ideal regulator for your gas meter may prompt you to make costly cylinder or regulator changes.


How to Select the Right Specialty Gases for Your Practice

Industries, laboratories, refineries and petrochemical industries understand the importance of specialty gases in their operations. Advancements in science and technology have pushed up the demand for extremely pure gases (about 99.995% purity) with equally high accuracies for specific industry and laboratory applications. As such, gas companies have put their best foot forward to manufacture special gases that meet their clients’ specifications. These gases that correspond to these special requirements are called specialty gases.

With many institutions and industries embracing specialty gases, the global specialty gas market is expected to grow at a CAGR of 6% or more between 2017 and 2021. This prediction by Technavio’s market research analyst seems to hold much truth, in light of the prevalent situation on the ground.

Selecting the Right Specialty Gas

If it’s your first time purchasing specialty gases, then you may need some guidance on how to go about the task. It is imperative to get the correct calibration gases and regulators to suit your particular needs and requirements. The manufacturers of specialty gases built them to very precise standards and stringent benchmarks to ascertain the quality of their products and ensure the safety of operations. It, however, falls on you to ultimately decide the correct gas for your use. Here is how you can find the correct specialty gas for your particular needs.

1. Do You Have Corrosive Gases or Liquids in Your Working Environment

Depending on whether you work in conditions with corrosive gases or liquids, your choice of specialty gas will vary greatly. The construction materials of these gas cylinders are specific to non-reactive liquids and gases. For environments with corrosive gases in their dry state, highly corrosion-resistant steel is always a preferred choice. Aluminum cylinders also work but with slightly corrosive gases and liquids that don’t severely degrade materials. Aluminum gas regulators are also lighter than steel cylinders and are a cheaper alternative too.

2. Should You Get a Single-Stage or Dual-Stage Regulator

Calibration gases come in a wide variety of single-stage regulators and dual-stage regulators. Single-stage regulators reduce cylinder pressure in one step to deliver pressure as per a particular range. They are best suited for applications where the pressure of delivery need not be constant. These applications, however, still need gas pressure to be within a particular range for smooth operations. Dual-stage regulators are specifically designed for processes and operations that require constant pressure during supply. Dual-stage regulators maintain the same pressure at the outlet of the cylinder.

There are also special types of cylinders for calibrator gases for specific industry applications. These cylinders with special regulators find use in cases where single or dual-stage regulators won’t suffice. Demand for excessively high pressures or use in highly corrosive environments may warrant the use of these special types of regulators.

3. You May Need a Custom Calibration Gas

Institution and industry requirements vary across the board, and the specific types of calibration gases available may not meet your particular needs. Using modern gravimetric and volumetric tools, gas manufacturers make special calibration gases standards that meet specific client requirements. These specialty gases are a result of highly sensitive instrumentation and very precise scaling. You can also find cylinders of various sizes to meet your work volume with these special calibration gases.

4. What Cylinder Size Do You Require?

Disposable calibration gas cylinders come in various sizes. The most common sizes include 10, 34, 58 and 110 liters. There are also custom-sized cylinders which some gas companies may offer upon request. Of course the larger the cylinder, the greater the price you’ll have to pay for the calibration gases.

Purchasing Calibration Gases Is Simple

Once you have these four considerations in check, you are better placed to buy the right calibration gas for your specific applications. Remember to take the necessary precautions before handling calibration gases as they might be toxic or flammable. Also, note that you can easily refill calibration gases on exhaustion.
