Multiple Gas Analyzer #5 + Sulfur

Many analysts require natural gas analysis for various applications. Frequently, sulfur compounds are also of interest.

 

Because low sulfur concentrations (<50 ppm) are difficult to measure, SRI has enhanced our popular Multiple 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 sulfur-inert 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 an inert 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 molecular sieve and HayeSep D) requires column temperatures of 250°C 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.
