FSUE “SPA “Analitpribor” is one of the leaders of gas-analysis instrument engineering in the Russian Federation. Production of gas-analysis equipment is from 1960.
ХРОМАТ-900 - stream gas chromatograph

Fixed automatic gas chromatographs Хромат-900 are designed for qualitative and quantitative analysis of gas (vapor) phases of organic and inorganic substances at monitoring of technological processes, such as :

Хромат – 900-1, -2 – for component analysis of gas at installations of rectification and raw hydrocarbon pyrolysis, cracking, impurity content in pure gases, determination of component content of hydrocarbon gases, combustion heat, relative density, Wobbe index, including natural, liquefied, coke oven or  associated gases, analysis of combustion gases injected into the atmosphere, contaminants measuring at the level of maximum permissible concentration in atmosphere and maximum permissible concentration in working area etc.;

Хромат – 900-3 – for component analysis (hydrocarbons, oxygen, nitrogen, carbon dioxide) and sulfur content (hydrogen sulfide, mercaptans) of hydrocarbon gases, including natural, liquefied, coke oven or  associated gases, technological process monitoring  in desulphuration systems etc.;

Хромат – 900 –4 for sulfur content analysis (hydrogen sulfide, mercaptans) of hydrocarbon gases, including natural and associated gases, technological process monitoring in Claus kilns, in desulphuration systems etc.;

Хромат –900 –5 for measuring of mole fraction of nitrogen, oxygen, carbon dioxide , hydrocarbons С1 – С5  and С6 + higher contained in flammable natural gas and calculation, on the basic of measured component content, physicochemical parameters of flammable natural gas quality– combustion heat, density, relative density and Wobbe index according to ГОСТ 31371.1-2008, ГОСТ 31371.2-2008, ГОСТ 31371.7-2008, ГОСТ 31369-2008, ГОСТ 31370-2008.

Application: plants of chemical, petrochemical industry, plants of production, transportation, processing and consumption of natural gas, gas mains, gas distribution organizations, including business accounting between business entities.

Sampling – stream forced.
Types of used sensors: ДТП – heat conduction sensor, ЭХД – electrochemical sensor.
