Summary:To develop an analytical method that can quantify an isothiocyanate.SOLUTION: A solid-phase micro extraction method is used to perform a quantitative analysis by gas chromatograph mass spectrometry (GC-MS). Preferably, diethyl disulfide and/or naphthalene-d8 are used as internal standard substance. Also preferably, the isothiocyanate is at least one selected from the group consisting of allyl isothiocyanate, isobutyl isothiocyanate, 1-propyl isothiocyanate and 2-phenylethyl isothiocyanate.SELECTED DRAWING: Figure 1 【課題】イソチオシアネート類を定量できる分析方法を開発することを課題とする。【解決手段】固相マイクロ抽出法を利用し、ガスクロマトグラフ質量分析法（ＧＣ-ＭＳ）によって定量分析を行う。また、内部標準物質としてジエチルジスルフィド及び／又はナフタレン-d8を使用することが好ましい。さらに、前記イソチオシアネート類が、アリルイソチオシアネート、イソブチルイソチオシアネート、1-プロピルイソチオシアネート及び2-フェニルエチルイソチオシアネートからなる群より選択される少なくとも一種であることが好ましい。【選択図】図１
