Process GC PGC 90.50

PGC 90.50 – is a reliable, time-tested development, combining the European technology adapted to the specific conditions of the Russian operation. Chromatograph has a modular construction, it can be used for both classical chromatographic analysis and for the analysis of hydrogen sulfide and mercaptans in petroleum and analysis hydrogen sulfide and carbon dioxide in amine absorbents (using patented modules).

  • Classic chromatographic analysis
  • Analysis of hydrogen sulfide and mercaptans
  • Analysis of hydrogen sulfide and carbon dioxide in amine absorbents


Chromatographs PGC 90.50 perfectly show themselves in the analysis of polluted and acid gases due to the use of classical chromatographic columns, which is easy to maintain and optionally regenerate by purging at any laboratory. Supplied with a spare set of chromatographic columns and spare parts for two years of operation. The device automatically disconnects the power in case of absence of a carrier gas.


  • Analysis of gas component composition according to GOST 31371,7, ISO 6974
  • Analysis of sulfur compounds in natural gas according to GOST 53367, ASTM D 7493, ISO 19739
  • Analysis of H2S and CO2 in the amine absorbents MVI 07101.00181-2008 / 2011
