In addition, Quadrex offers high volume Nitrogen Generators for LC/MS applications and high purity Nitrogen Generators, high purity Hydrogen Generators, and Zero-Air Gas Generators for GC or other lab applications. The GC gas generators are of a stackable and modular design, utilizing minimal laboratory floor space. 

Most generators are available with built-in air compressors (where applicable) for easy installation and use.  Improve laboratory safety and reduce or eliminate the costs and labor involved in changing cylinders. These Gas Generator Systems produce greater stability and repeatability, eliminating cylinder to cylinder variations, and allow you to run your instruments 24 hours a day with safety and confidence.  Don’t buy your gas, make it!

Also available are full-featured portable GCs from SRI Instruments.  SRI offers preconfigured GC systems for many common applications such as Multi-Gas Analysis, Biodiesel, Mud-logging, Environmental/BTEX, Explosives and more.

SRI GCs can be custom configured to your specific requirements with many standard injector and detector options, gas sampling valves, etc.  The SRI GCs are ruggedly built and are ideal for use in the field but are equally comfortable on a lab bench.  Each SRI GC includes Peaksimple Data Acquisition software and a 2 year warranty.
