Description
(1)図2に示す如く、キャピラリー14に微小な穴を開けてキャピラリー14に電極22を直接埋め込み、接着剤24で固定して電気泳動を行う方法(非特許文献1)。
(2)図3に示す如く、キャピラリー14の出口に導電性金属(例えば金など)26を蒸着させて電気泳動を行う方法(非特許文献2)。
(3)キャピラリーの途中に泳動液リザーバーを設けて通常の電気泳動を行いながら、泳動液中の化合物を電気浸透流(電圧を印加した際に自然発生する液流)EOFを利用してオフラインで泳動させる方法(非特許文献3)。
(i)キャピラリー電気泳動(CE)の分析条件
キャピラリー14には、様々な内径のフューズドシリカキャピラリー(例えば内径50μm、外径360μmなど)を用いることが可能である。緩衝液16には、10%(v/v)酢酸(pH約2.2)を用いた。印加電圧は、+30kV、キャピラリー温度は20℃で測定した。試料は、加圧法を用いて50mbarで15秒間注入した。
(ii)飛行時間型質量分析計(TOFMS)の分析条件
正イオンモードを用い、イオン化電圧は1.8kV、フラグメンター電圧は175V、スキマー電圧は50V、OctRF電圧は100Vに設定した。乾燥ガスには窒素を使用し、温度300℃に設定した。質量電荷比(m/z)50〜1,000までの化合物を対象に、スキャン速度1.5サイクル/秒で測定を行った。
(iii)三連四重極型質量分析計(QqQMS)の分析条件
正イオンモードを用い、イオン化電圧は2.4kV、フラグメンター電圧は90Vに設定した。乾燥ガスには窒素を使用し、温度300℃に設定した。多重反応モニタリング(MRM)法によって、各化合物名に最適化されたプレカーサーm/z、プロダクトm/z、コリジョンエネルギーにて測定を行った。
