| 概要 |
メチルメルカプタンと硫化水素の2つの臭気物質を，公定法で規定のFPD付ガスクロマトグラフ(GC-FPD)装置より汎用的なイオンクロマトグラフ(IC)装置で同時計測する際の技術的課題を抽出した。水酸化カリウム含有過酸化水素水を気体試料捕集液に用い，検量線の直線性や気体試料からの2物質の回収率を複数の分析条件で比較した。また，水産廃棄物由来模擬臭気中の2物質の測定値をICとGC-FPDで比較した。その結果，実施したIC分析では測定値のばらつきが大きく，捕集液pHの管理などが課題であることがわかった。（再掲2021/11/29:原稿受付日訂正・本文内５ヶ所修正） |
| Abstract |
Technical problems were investigated in the simultaneous measurement of two odorous sulfur compounds, methyl mercaptan and hydrogen sulfide, using ion chromatography (IC) which is more commonly used than FPD-equipped gas chromatography (GC-FPD) designated in the official measurement method in Japan. Hydrogen peroxide solution with potassium hydroxide was utilized as the gas collecting liquid, and the linearity of calibration curves and the recovery ratio of two compounds from gas samples were compared among several measurement conditions. Next, the measurement values of these two compounds in the model odor derived from fisheries waste were compared between IC and GC-FPD. Results showed that scattering of the measured values were seriously large in this studyʼs IC analysis, then pH management of the gas collecting liquid and some other matters were found as the future problems. |
