Use the following decision tree to help narrow your equipment selection.
Calibration gas is a reference gas used as a comparative standard in the calibration of analytical instruments, such as gas analyzers or gas detectors.
Hydrogen may be used as a flame gas or as a carrier gas for GC and GC/MS applications. Various methods may be employed to produce and purify hydrogen.
Nitrogen generators are designed to cater to the requirements of LC/MS, LC/MS/MS, Sample Evaporators, ELSD and NMR applications.
TOC generators produce hydrocarbon-free, CO2-free compressed combustion / carrier gas for TOC analyzers, and supply gas for total organic halogen analyzers.
Zero Air Generators produce highly pure air with gas purity below 0.05ppm total hydrocarbon content and are used for GC with FID, FPD, and NPD detectors, as a support gas for total hydrocarbon analyzers, and as an exhaust gas for LC/MS instruments.
Zero nitrogen generators produce suitable carrier gas and make-up gas at trace detection limits.
