DIN EN ISO 19739:2009 天然气.气相色谱法测定硫化合物的含量(ISO 19739-2004).德文版本EN ISO 19739-2005 + AC-2009
Natural gas - Determination of sulfur compounds using gas chromatography (ISO 19739:2004) (includes Corrigendum AC:2009); English version of DIN EN ISO 19739:2009-08
This International Standard specifies the determination of hydrogen sulfide, carbonyl sulfide, C1 to C4 thiols,
sulfides and tetrahydrothiophene (THT) using gas chromatography (GC). Depending on the method chosen
from those given in the annexes, the application ranges for the determination of sulfur compounds can vary,
but whichever of the methods is used, the requirements of this International Standard apply.
