Determination of sulfide gas analysis
Flame photometric gas chromatography
1 Scope
This standard specifies the use with flame photometric detector (FPD) of the gas chromatograph gas total sulfur, total sulfur and organic form of sulfur
method.
This standard applies to gas total sulfur hydrogen, oxygen, nitrogen, carbon dioxide, methanol synthesis gas, ammonia synthesis gas, dry gas, coke oven gas,
Determination of total sulfur in the form of organic sulfur and total sulfur measurement range (in terms of sulfur) was 0.07mg/m3 ~ 2mg/m3, forms of sulfur measurement range (in
Hydrogen sulfide sulfur meter) of 0.07mg/m3 ~ 7mg/m3.
