Laboratory gas generators deliver purified gas directly to systems including gas chromatographs, environmental chambers, and other applications that require clean, dry gas such as hydrogen and nitrogen. Gas generators are also safer as they limit the amount of flammable and compressed gas, often stored in gas cylinders, in your lab. Though the upfront costs of gas generators are high, replacing your gas cylinders with a gas generator can lead to increased convenience and decreases in overall costs. For a list of gas generator manufacturers, see our online directory:

5 Questions to Ask When Buying Gas Generators/Specialty Gases:

  1. What type of gas do you require for your application?
  2. What gas purity do you require?
  3. Which analytical instrument will the generator be paired with, and is it compatible?
  4. How much space will the gas generator take up in your lab?
  5. Does the generator meet all relevant regulations (CSA/ETC, EC, EMC, etc.)?

Extend Generator Lifespan

Regular maintenance is integral to generator longevity. Consistently changing filters and maintaining parameters such as temperature and humidity are essential to maximizing the lifespan of your gas generator. Learn more about how you can keep your generator performing effectively at

Cleaning with a Generator

While gas generators are predominantly utilized for analytical applications like gas chromatography, they can also be used to keep labs disinfected and sterilized. If a lab handles biohazardous substances, gas generators that deliver gases including chlorine dioxide, ethylene oxide, and vaporized hydrogen peroxide can provide for faster, safer, and more effective surface disinfection and sterilization than manual cleaning.
