CA 2706531

An ion-ion reaction cell is provided comprising a plurality of electrodes (1) forming an ion guide ()2. A transient DC voltage wave is applied to the electrodes (2) in order to load reagent anions into the ion guide (2). Analyte cations are then subsequently transmitted through the ion-ion reaction cell by a subsequent transient DC voltage wave. Ion are arranged to undergo ion-ion reactions within the reaction cell and the resulting fragment ions which are formed within the reaction cell are then subsequently translated out of the reaction cell by means of a transient DC voltage wave.

L'invention concerne une cellule de réaction ion-ion comportant une pluralité d'électrodes (1) formant un guide d'ions (2). On applique une ondulation transitoire de tension continue aux électrodes (2) pour charger des anions d'un réactif dans le guide d'ions (2). On transmet ensuite des cations de l'analyte à travers la cellule de réaction ion-ion par une autre ondulation transitoire de tension continue. Les ions sont disposés de façon à subir la réaction ion-ion dans la cellule de réaction et les ions de fragments résultants qui sont formés dans la cellule de réaction sont ensuite évacués de la cellule de réaction au moyen d'une ondulation transitoire de tension continue.
