Multiple
Gas Analyzer's from Buck Scientific
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,
Buck 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 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.
