Title (EN) METHOD FOR QUANTITATIVELY DETERMINING ANIONIC COMPOUND BY CE/MS
(FR) PROCÉDÉ DE DÉTERMINATION QUANTITATIVE D’UN COMPOSÉ ANIONIQUE PAR EC/AM
(JA) CE/MSによる陰イオン性化合物の定量分析法
Abstract:
(EN) This invention provides a method for separating and analyzing an anionic compound by combining capillary electrophoresis with mass analysis. The method comprises the step of setting, as an anode, the inlet side for a migration liquid in a capillary filled with the migration liquid and setting, as a cathode, the outlet side, applying voltage to the capillary to conduct electrophoresis of a sample containing an anionic compound, the electrophoresis being carried out so that the absolute value of the mobility of electro-osmosis flow generated upon the application of voltage exceeds the absolute value of the mobility of the electrophoresis of at least one anionic compound in the sample; and the step of subjecting the anionic compound in the sample migrated to the outlet of the capillary to mass analysis.
(FR) La présente invention concerne un procédé de séparation et d’analyse d’un composé anionique par combinaison d’électrophorèse capillaire et d’analyse de masse. Le procédé comprend l’étape de réglage, en tant qu’anode, du côté d’entrée pour un liquide de migration dans un capillaire rempli du liquide de migration et le réglage, en tant que cathode, du côté de sortie, avec application d’une tension au capillaire pour réaliser l’électrophorèse d’un échantillon contenant un composé anionique, l’électrophorèse étant effectuée de manière à ce que la valeur absolue de la mobilité du flux électro-osmotique généré par l’application de la tension soit supérieure à la valeur absolue de la mobilité de l’électrophorèse d’au moins un composé anionique dans l’échantillon. Le procédé comprend également l’étape de soumission du composé anionique dans l’échantillon migré vers la sortie du capillaire à l’analyse de masse.
(JA) 本発明は、キャピラリー電気泳動と質量分析とを組み合わせて陰イオン性化合物を分離分析する方法を提供し、該方法は、泳動液で満たされたキャピラリーの泳動液の入口側を陽極および出口側を陰極となるように設定し、該キャピラリーに電圧を印加して陰イオン性化合物を含む試料を電気泳動する工程であって、該電圧の印加により発生する電気浸透流の移動度の絶対値が、該試料中の少なくとも1種の陰イオン性化合物の電気泳動移動度の絶対値を上回るような条件で該電気泳動を行う、工程;および、該キャピラリーの出口まで泳動された該試料中の陰イオン性化合物を質量分析する工程;を含む。
