Permanent gases analyzer

The continuous or discontinuous mode permanent gases monitor for laboratory or online.

A highly automated system for routine measurement of permanent gases on the range : ppb or ppm.

  • Process : H2 / N2 / O2 / Ar / Kr / Xe / CO* / CO2 / CH4
  • Quality control in pure gas
  • Impurities in Hydrogen
  • Substance tracer
  • Gas input in tubing
  • NH3 in ambiant air
  • CO / *CO2 in ambiant air
  • CO in *C2H4
  • Impurities in CO2

* Can be analysed by chroma CO ( FID methaniser )

Chroma DID is easy to use for ppm and % range.
