AP2E ProCeas H2 purity analyzer

The AP2E ProCeas "H2 purity analyzer" is a fully pre-calibrated laser infrared spectrometer for the detection of ppb-level impurities in the to be measured hydrogen streams.

It is using the patented OFCEAS IR laser technology for improved specificity, selectivity, accuracy and stability to prevent a instrumental response drift.

The "ProCeas H2 Purity Analyzer" is also using a patented low-pressure sampling system enabling low-cost installation thank to non-heated lines and reduced maintenance.

With the H2 Purity Analyzer, methane (CH4), hydrogen sulfide (H2S), carbon monoxide (CO) and carbon dioxide (CO2) can be measured in the ppb range of the hydrogen streams.

Selected highlights (sampling):

  • flow rate: 3 - 9 l/h
  • max. temperatur: 600 °C
  • max. humidity: H2O(g) < 65% vol. - Standard /  H2O(g) > 65% vol. - Study Required
  • pressure: 1 atm ± 100 mbar at sampling point.
