D7493-Test Method for Online Measurement of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatograph and Electrochemical Detection

The precision of this test method is based on an interlaboratory study of ASTM D7493- Test Method for Online Measurement of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatograph and Electrochemical Detection, conducted in 2018. Each of 5 “laboratories” has tested 3 different analytes: Tetrahydrothiophene, (THT), Hydrogen Sulfide (H2S) and Methyl Mercaptan (Meth SH) at 3 different concentrations. Every “test result” represents an individual determination. Practice E691 was followed for the design and analysis of the data.
