Summit-FAS can provide fast GC analysis for C1-C10 hydrocarbons by micro-TCD (thermal conductivity detector) using the Agilent 490 Micro TCD system. The Agilent micro-TCD is a state of the art modular GC system that analyze C1-C5 hydrocarbons in <30 seconds which further aids in data resolution while maintaining the peak separation necessary for gas ratio analysis. Separate modules are available for helium and H2S analysis. The ability to analyze CO2 and H2S by chromatographic methods can be an advantage over typical gas sensors.
CO2 gas sensors that use infrared detection are particularly sensitive to water/moisture and do not have low sensitivity. H2S sensors may have sensitivity to other compounds. Both compounds can be lagged and reported on a mudlog along with the C 1-C5 data.
