- W2314971543 abstract "ガスクロマトグラフィーでたばこアルカロイドを分析する際の固定相液体の種類,量,分離管温度,流速,担体の種類,粘度などが理論段高さ,感度などに及ぼす影響を調べ,性質類似のニコチン同族体を分離する際の操作条件について検討した.理論段高さはある流速において最小の値を示し,また,この値は固定相液体(PEG 6000)の量が3～24%では液体量が増加するに従って小さくなり,分離管効率が向上する.また,理論段高さが最小の値を示す流速(100ml/min前後)では,分離管温度は160～180℃のときに最小の値を示す.担体はセライトよりもC22のほうが,また粒度は細かいほうがよい.試料注入量を減らすと理論段高さは顕著に向上し,また感度も増大する.以上の結果から,ノルニコチンとミオスミンを分離するためには液体量24%,温度180℃,流速80ml/min,試料注入量1μl,分離管長2mで分析すればよいことがわかった." @default.
