This test method is used for the determination of Sulfur compounds in natural gas and gaseous fuels by gas chromatography (GC) with pulsed flame photometric detection (PFPD). Below is a complete list of Sulfur compounds that Capco Analytical Services, Inc. test for on a regular basis.
Testing for Hydrogen Sulfide, Carbonyl Sulfide, Methyl Mercaptan, Ethyl Mercaptan, and Dimethyl Sulfide.
|Source||Common Sulfur Compounds|
|Sewer and Wastewater Treatment Facilities||Hydrogen Sulfide, mercaptans, dimethyl sulfide|
|Petrochemical Refineries||Hydrogen Sulfide, carbonyl sulfide, carbon disulfide|
|Odorants of Liquid Propane||Ethyl mercaptan, dimethyl sulfide|
|Pulp and Paper Mills||Hydrogen sulfide, methyl mercaptan, dimethyl sulfide|
|Composting Facilities||Hydrogen sulfide, ethyl mercaptan, dimethyl sulfide, methyl mercaptan|
|Live Stock Activity||Hydrogen sulfide, dimethyl sulfide, carbonyl sulfide|
Collection, Shipping and Analysis
Since many sulfur compounds are not stable in stainless steel canisters, such as Summa canisters, air samples for this analysis should be collected in Tedlar bags.
Due to the unstable and reactive nature of many sulfur compounds, full compliance of the method requires analysis of the samples within 24 hours of collection. Despite this short holding time Capco Analytical Services, Inc. receives samples from all over North America and performs analysis within holding time on a daily basis.
