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.
