A wide range of fields and industries rely on laboratory gases for their applications, most notably chromatography and mass spectrometry. It is crucial to select the carrier gas best suited for chromatography applications, as the type of carrier gas used to move the solutes through the column directly impacts the efficiency of the separation. There are several other important factors to consider when selecting a carrier gas, including safety, sustainability, and cost.
Gas generators are a safe and sustainable alternative to compressed gas cylinders, and can generate a continuous supply of highly pure hydrogen, nitrogen, and oxygen. In addition to eliminating the sustainability challenges associated with tanks—energy-intensive processes for generating and compressing gas, replacing old tanks, and transporting them—hydrogen and nitrogen gases are more sustainable alternatives to helium. Helium is a non-renewable resource that requires considerable energy use to extract.
Labs can also enhance safety by ending their reliance on compressed gas cylinders. These cylinders (which must be regularly replaced) pose risks such as leaks and potentially even explosions if not handled correctly.
An in-house supply of laboratory gases can also be a more cost-effective approach. While a generator is a larger initial investment, the lab may see savings within one year of use—even if it replaces a single compressed gas cylinder.
Choosing the right carrier gas for your lab requires some research and comparison. The delivery method is also an important consideration, as it directly impacts safety, sustainability, and cost. Taking time to evaluate what your applications require will ensure a safe and reliable solution for your lab.
