초록

본 연구에서는 Triple-bed 흡착튜브를 제작하여 열탈착장치와 GC-MS로써 다성분 복합 악취성물질 및 휘발성유기 화합물을 동시분석 가능성을 평가하고자 하였다. Triple-bed 흡착튜브는 하나의 튜브에 Tenax-TA와 소량의 Carbopack B 및 Carbosieve SIII 흡착제를 흡착강도 순으로 3단 배열된 것이다. GC-MS의 분석조건은 mass range 20~350 m/z, 불순물 1 ppm 이하의 헬륨을 운반가스로 하여 저비점 저분자량 물질의 분리동정에 효과적일 수 있도록 하고, 목적이온 추출을 통하여 정량하였다. 그 결과 ppbv 수준의 C1~C5의 알콜(4), 알데히드(6), 케톤(2) 그리고 황화합물(2)을 포함한 14종의 물질 모두 99%이상의 회수율과 양호한 재현성 및 직진성으로 동시분석이 가능하였다. 비교적 휘발성이 강하고 분자량이 낮은 물질인 메틸알콜, 아세트알데히드는 상대습도 45% 이하, 흡착유속 50 mL/min, 흡착량 2 L 이하에서 높은 회수율로 보다 안정적으로 정량분석이 가능하였다. 또한 목적이온 추출은 물질피크가 겹쳐 나타난 경우에도 다 성분 물질을 각각 정량 가능하였다.

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.
