Many analysts require natural gas analysis for various applications. Frequently, sulfur compounds are also of interest.
Because low sulfur concentrations (<50ppm) are difficult to measure, SRI has enhanced our popular
to simultaneously monitor low levels of sulfur compounds. The additional hardware required is an
, 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.
