Abstract
속빈 섬유-액상 미량추출법(hollow fiber-liquid phase microextraction, HF-LPME)과 기체 크로마 토그래프/질소-인 검출기(GC-NPD)를 사용하여 사람의 뇨와 여러 가지 음료 중에서 극미량의 카페인을 분석하는 방법을 확립하였다. 수용액 시료로부터 카페인의 양을 측정하기 위해서 속빈 섬유의 길이, 추 출용매의 종류, 교반효과, pH 및 염석효과 등 여러 가지 실험적인 파라미터를 변화시켜서 최적의 조건을 확립하고자 하였다. 검정곡선의 회귀계수(r2)는 0.9994이상이었으며, 평균 상대 회수율은 102%(n=3)이었 으며, 기기검출한계는 2.5 ng/mL, 정량한계는 10 ng/mL이었다. 확립된 HF-LPME 방법은 생물학적 시료, 음식물, 환경시료 중에서 카페인의 농도를 측정하기에 편리하고 정확한 방법이 될 것이다.
