The objective of this study is to assess feasibility of simultaneous analysis for trace multi-components odorous and volatile organic compounds using a Triple-bed adsorbent tube with a thermal desorber and GC-MS. Triplebed adsorbent tube is 3 bed packed Tenax-TA with small amount of Carbopack B and Carbosieve SIII in order of adsorption strength in a tube. The operating conditions of GC-MS was possibly able to and effectively detect high volatile and low molecular weight compounds at the mass range of 20~350 m/z using a below impurity 1ppm of Helium carrier gas, of which quantitatively analyzed by target ion extracts. According to the experiment, C1~C5 of 14 components; sulfur containing compounds(2), ketones(2), alcohols(4) and aldehydes(6) were simultaneously analyzed with recoveries of 99%, and good repeatability and linearity. High volatile and low molecular weight compounds such as methyl alcohol and acetaldehyde can be safely quantified with high recovery at a condition of 50mL/min of flow rate, below 2L of adsorption volume, and 45% of relative humidity. Target ion extract can also simultaneously quantify multicomponents with odorous and volatile organic compounds in an occasion of piled up two peaks.
