To analyze trace-level, reduced sulfur compounds (RSC) in ambient air, gas chromatography (GC) is used as the commonest method. The GC-based analysis is generally conducted by transferring samples via direct injection into GC or by the combined treatment of cryofocusing (CF) and thermal desorption (TD). In this study, experimental bias involved in GC analysis is examined by evaluating the calibration properties of each transfer approach. To this end, the detection properties of RSCs were evaluated with respect to the two major variables of sample concentration and sample volume. The recovery rate of TD application was also discussed based on the most recent findings in which its recovery rate is compared against the results derived by the direct injection method. The overall results suggest that the TD-based analysis of RSCs can be optimized by unifying the experimental conditions between sample and standard gases.
