In this study, the recovery rate of Tedlar bag (T) sampler was investigated in comparison to polyester aluminum bag (P) sampler. To derive the comparative data sets for the relative performance between different samplers, a series of calibration experiments were performed by using 1 ppb standard of four offensive reduced sulfur compounds (RSC) odorants (H₂S, CH₃SH, DMS, and DMDS) along with SO₂ and CS₂. All the analysis was made by gas chromatography/ pulsed flame photometric detector (GC/PFPD) combined with air server/thermal desorber (AS/TD). The measurement data were obtained by loading gaseous standards (1 ppb) at 3 injection volumes (250, 500 and 1,000 ㎖) at three intervals (0, 24 and 72 hrs). The recovery rates (RR) of P sampler were computed against the slope values of T sampler. According to our analysis, P sampler exhibits slightly enhanced loss relative to T, especially with light RSCs (H₂S and CH₃SH). At day 0, RR for the two were 88 and 85%, respectively. Such reduction proceeded rather rapidly in the case of H₂S through time. However, P sampler was more stable to store SO₂ unlike others. Despite slightly reduced recovery, P sampler appears as a good replacement of T sampler.
