Hitachi LaChromUltra 2000U를 사용하여 역상의 초고속액체크로마토그래피 방법으로 식품 중의 PAHs 14종을 신속하게 분석하는 방법을 개발하였다. PAHs분석을 위한 방법은 solid phase extraction (SPE)법에 의한 정제 후 u-HPLC를 사용하여 형광검출기로 분석하였다. 이 분석법은 감도가 매우 좋았으며, 식품 중의 PAHs를 <TEX>${\mu}g$</TEX>/kg수준에서 분석이 가능하였다. 6개의 시료를 분석한 결과 모든 시료에서 PHE가 검출되었고, 그 함량은 2.5~19.9 <TEX>${\mu}g$</TEX>/kg이었다. Benzo[c]fluorine (BCL), pyrene (PYR), benzo[a]anthracene (BaA), chrysene (CHR), benzo[b]fluoranthene (BbF), benzo[k]fluoranthene (BkF) 이 <TEX>${\mu}g$</TEX>/kg이하의 농도에서 검출되었으나 그 농도는 모두 정량한계 이하이었다.
Using a Hitachi LaChrom Ultra 2000U, a reverse phase ultra high performance liquid chromatography (u-HPLC) method was developed for the rapid quantification of 14 PAHs in foods. The proposed method for PAH analysis is based on solid phase extraction (SPE) cartridges; the determination was carried out by u-HPLC with fluorimetric detection. The method was very sensitive; PAH concentration levels were in a low μg/kg range and could be detected and quantified. Six samples of food were analyzed. Among PAHs, PHE was found in most of samples, the concentration ranging from 2.5 to 19.9 μg/kg. The contents of benzo[c]fluorine (BCL),pyrene (PYR), benzo[a]anthracene (BaA), chrysene (CHR), benzo[b]fluoranthene (BbF), benzo[k]fluoranthene (BkF) were low at the ‘μg/kg’ level or were less than LOD.
