초록
식품포장재에 함유되어있는 톨루엔 및 잔류용제를 용출분석하는 방법으로 headspace gas chromatography (static headspace method)를 이용하였다. 5종(methanol, isopropyl alcohol, ethyl acetate, methyl ethyl ketone, toluene)의 표준용제에 대한 머무름시간과 상대표준편차를 검토해 본 결과, 이상적인 머무름시간의 상대표준편차라 할 수 있는 0.15% 이하로 양호하였으며 재현성도 우수하였다. 인쇄된 포장재를 분석한 결과. 주로 methanol, toluene, methyl ethyl ketone이 검출되었고, methanol은 불검출
A static headspace gas chromatographic (HSGC) technique was used to quantify toluene and other solvents (methanol, isopropyl alcohol, methyl ethyl ketone and ethyl acetate) in food packaging films. Comparison of retention times and coefficient variations for standard solvents showed consistent retention time and good reproducibility. Therefore, this method using static HSGC proved to be superior in rapidity and reproducibility, and is thought to be adaptable to analysis of a large number of samples. The methanol content was
