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
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.
