Abstract
In this study, we have developed a cryogenic concentration system for the analysis of non-methane hydrocarbons (NMHCs) in air sample. NMHCs with nmol/mol level of concentrations in the atmosphere were quantified by a comparative method with certified reference gas mixture. GC/FID with cryogenic concentration system operated in the range from -67 oC to 180 oC was adopted. After cryogenic concentration, a fast desorption by heating could achieve a large amount of sample injection into the GC/FID. The linearity of the system was verified with the peak areas of NMHCs of the concentration amount of sample. The reproducibility is less than 10% and the limit of detection (LOD) is 0.1 nmol/mol. For the application of this system, we analyzed NMHCs in gas samples taken from air and soil in Daejeon, Seosan and Goheung.
