Laboratory Gas Generators

Compressed gases have become an integral part of the laboratory. For many laboratory scientists, gases like hydrogen and nitrogen are used on a daily basis and are often taken for granted. The expense, concerns of safety, and unexpected downtimes have motivated users to alter their approach and institute laboratory gas generators. Instead of using cylindered gases to supply the carrier or fuel gas supply, an increasing number of laboratories have become accustomed to using laboratory gas generators, which can supply gases for analytical instruments such as GC, LC–MS, NMR, Purge, and others.

Gas generators employ different technologies, depending on the type and purity of the gas needed. The use of membranes and specialized adsorbents make it possible to generate gas, such as nitrogen, at very high purity levels (99.99999% purity). Improvements in compressor designs and electronic controls have strengthened the performance and value of gas generators in the laboratory. Major types of gas generators include nitrogen, hydrogen, TOC, zero air, oxygen, and ozone generators.

North American and European laboratories dominate the laboratory gas generators market with a combined share of about two-thirds. North American laboratories have embraced this technology particularly with the rising cost of cylinder gases and concerns of safety and purity. Depending on the application, a lab could effectively recover the initial cost of a gas generator within several months of the purchase and, in the long-term, could save tens of thousands of dollars per year.
