Abstract
SPME 분석기법은 헤드스페이스(Headspace: HS) 방식으로 기체상태의 흡착을 유도하거나, 액상시 료에 직접 접촉하는 방식으로 분석대상 물질을 추출할 수 있다. 본 연구에서는 CAR/PDMS fiber를 이용하 여, 액상시료의 VOC 분석을 시도하였다. 3 가지 변수 (흡착온도, 흡착시간, 교반여부)의 강약을 동시에 감 안한 8가지 조합조건에서 분석효율을 조사하였다. (1) 용출온도: 30 대비 50oC. (2) SPME fiber 시료노출 시간: 10과 30 min. (3) 교반적용 여부: 무 교반 대비 1200 rpm. 8가지의 조합형 분석조건에서 HS-SPME 방식을 적용하여 분석한 결과, S50-30 (stirring speed: 1200 rpm, exposure temp: 50oC, exposure time: 30 min) 에서 가장 분석효율이 높게 나타났다. 가장 좋은 감도를 보인 S50-30방식의 분석 회수율을 GC에 직접주 입하는 방식을 임의의 기준으로 평가하였을 때, 성분에 따라 상대 회수율이 45.5~68.5%로 나타났다. 본 연구의 결과, 3가지 변수 중에서 교반여부는 검량 특성을 결정짓는 가장 중요한 인자로 나타났다.
