Hydrogen is used in a number of areas, from industrial processes such as pesticide production and the removal of sulfur from petrochemical products to its use as a fuel and in power generation. To ensure the quality of hydrogen, standards such as ISO 14687 and GB/T 3634.2 have been produced which specify the maximum content of certain compounds in hydrogen gas. As such, it is of great importance that hydrogen gas refiners and those using hydrogen gas in various processes have access to a method which allows for quick, accurate and sensitive detection of these compounds. This application note shows the quantitation of carbon monoxide (CO), carbon dioxide (CO2) and methane (CH4) in hydrogen.
false falseAnalysis of carbon monoxide (CO), carbon dioxide (CO2) and methane (CH4) in hydrogen samples was performed with the PerkinElmer GC Engineered Solution.
The GC Engineered Solution with THC analysis consists of two analytical channels which include carrier gas input, a hydrogen input for the flame ionization detector (FID) a HayeSep Q analytical column, a restrictor for THC analysis and a methanizer for CH4 analysis. An important aspect of the analytical method is the backflushing of the analytical HayeSep Q column to speed up the analytical cycle, and to prevent the elution of water, ammonia, sulfur and any hydrocarbons other than methane which have the potential to poison the methanizer catalyst or extend the analytical cycle.
