Chromatographic method for rapid field determination of parts-per-million to percent level carbon dioxide in natural gas.
Amarillo, TX: U.S. Department of the Interior, Bureau of Mines, IC 9376, 1994 Jan; :1-7
The report describes a chromatographic method that is used for rapid field determinations of carbon dioxide in natural gas streams at a U.S. Bureau of Mines (USBM) helium production facility. The method employs a commercially available portable gas chromatograph that is equipped with a 10-m, fused-silica capillary column coated with a porous polymer. The instrument operating parameters permit determinations to be performed over a concentration range of 10 ppm to 10 percent with a frequency of 20 samples/hour. The speed at which determinations can be performed is an important factor when evaluating efficiency or troubleshooting processes at the helium facility.
