BRAND NEW Multiple Gas Analyzer + Sulfur GC Systems
Many analysts require natural gas analysis for BTU value calculations or drilling and mudlogging applications. Frequently, sulfur compounds are also of interest.
Because low sulfur concentrations (<50ppm) are difficult to measure, SRI has enhanced our popular Mulitple Gas Analyzer GC systems to simultaneously monitor low levels of sulfur compounds. The additional hardware required is an FPD/FID detector, which selectively detects sulfur down to mid-ppb range, and a room temperature Silcosteel sample loop.
One reason sulfur is so difficult to measure is that it disappears on contact with hot stainless steel surfaces; even limited contact with a hot stainless steel loop will destroy any sulfur in the gas sample. Our solution is to use a Silcosteel-lined transfer line leading to a splitter, and a 60-meter thick film capillary column. While Teflon columns are sometimes also used for sulfur analysis, the natural gas analysis (using MoleSieve and Silica Gel) requires column temperatures of 250oC or higher. Since the sulfur column is located in the column oven, it is essential to use a column like the 60-meter capillary which can tolerate the higher temperatures.
