Analysis of the C sub(1)-C sub(5) components of natural gas samples using gas chromatography-combustion-isotope ratio mass spectrometry

Recent developments in porous polymer fused silica capillary columns combined with high sensitivity GC-C-IRMS have enabled the routine analysis of the C sub(1) to C sub(5) compounds of natural gases without any prior sample preparation. The analysis time for the carbon isotope ratios of the individu...

Description
Summary:Recent developments in porous polymer fused silica capillary columns combined with high sensitivity GC-C-IRMS have enabled the routine analysis of the C sub(1) to C sub(5) compounds of natural gases without any prior sample preparation. The analysis time for the carbon isotope ratios of the individual components is reduced to that of routine GC-FID analysis. Selection of column type is critical to analytical performance. Analytical conditions have been determined which allow the separation and isotopic analysis of C sub(1), C sub(2), C sub(3), iC sub(4), nC sub(4), iC sub(5) and nC sub(5) in an aliquot of
