Top 3 Things You May Not Know About Gas Generators and Specialty Gases

1. Kipp’s apparatus, one of the earliest laboratory gas generators, was invented by Dutch pharmacist Petrus Jacobus Kipp in 1844. It was used for the preparation of small volumes of gases but fell out of use in laboratories once gases became available in cylinders.

2. The ongoing helium shortage has created a robust market for hydrogen in gas chromatography.

3. Those who use gases and/or gas cylinders in the lab know extreme care needs to be taken in their handling. Unfortunately there have been many accidents relating to gas cylinders over the years, most often due to unsafe procedures, with one of the worst occurring in March 2006 in a research laboratory building at University of Haute Alsace (France). A leak in a gas cylinder led to an explosion of ethylene in the enclosed lab, followed by a fire that burned for five hours. One professor was killed and a trainee seriously injured while 20 more people also sustained injuries.

Recently Released Gas Generators/Specialty Gases

Zero Nitrogen Generators

  • Designed to transform standard compressed air into a safe, regulated supply of 99.9995% pure nitrogen with 
  • Include a heated catalyst module and are specifically designed to replace P5 argon/methane mixtures as well as ultra-high purity nitrogen
  • Feature an economy mode which allows the generator to switch into standby mode when there is no demand from the downstream instrument

544 Series IntelliSwitch IIV Gas Distribution & Management System

  • Automatically switches between two high-pressure, high-flow gases to provide interchangeable service and continuous supply
  • Offers reliable high-flow, high-pressure switching in demanding applications and environments
  • Proprietary economization software virtually eliminates liquid cylinder vent loss and substantially reduces residual return
  • Web server allows for remote monitoring and email notification of events to users


NA1970 Double Cartridge Nitrogen Generator

  • Features a max nitrogen output of 80 LPM
  • Produces nitrogen gas to support up to 100 sample positions
  • Generates a 99.9% pure stream of nitrogen
  • Has a lower cost than some generators because this model must be used with an oil-less air compressor (not included)


FlexStream Modular Gas Standards Generator

  • Offers total flexibility for creating precision gas mixtures
  • Dilutes the emission from permeation or diffusion tubes with an inert gas, typically nitrogen or zero air, to create trace concentration—ppm, ppb, and pptr mixtures
  • Features up to six independently controlled channels
  • System can be controlled remotely by a PC or process computer using Modbus® connectivity
