Abstract

Determination of PFOS in instant food packing materials by LC-MS/MS was developed. The procedure involves an extraction of the Food Packing Materials with 100% methanol soxcelet extraction method. The LC separation was performed by Hypersil Gold ($150mm{\times}2.1mm$ 5 um) with mobile phases of 2 mM amoniumacetate solution and acetonitrile. The Mass spectral acquisition was done in negative ESI/SRM using the TSQ Quantum Ultra. With this method, good linear relationship, sensitivity and reproducibility were obtained. The rate of recoveries of PFOS from paper material spiked with 1.0 ug/L were 99.84%, respectively. The limit of quantitation and limit of detection were below 0.03 ug/L and 0.009 ug/L. The method had been applied to determination of PFOS in instant food packing materials.

퍼플루오르옥탄설포네이트를 LC/MS/MS를 이용하여 분석한 결과 분석 대상물질의 고유한 스팩트럼을 얻어 정량하여 머므름 시간은 4.33분이었으며 상관계수($R^2$)은 0.9998로 양호한 직선상의 그래프를 얻을 수 있었다. 퍼플루오르옥탄설포네이트에 대한 분석법의 회수율은 99.84%로 전반적으로 좋은 회수율을 보였으며 또한 이 연구에 적용되기에 충분한 정밀도와 정확도를 가지고 있음을 확인할 수 있었다. 퍼플루오르옥탄설포네이트 정량한계 및 검출한계는 0.03, 0.009 ug/L이었다. 따라서 식품 용기포장재에서의 분석에 적용이 가능하였다.
