Abstract

L'invention concerne les détecteurs d'ions négatifs. Elle se rapporte à un détecteur d'ions négatifs dans lequel un dispositif de transformation reçoit les ions négatifs et crée une quantité proportionnelle d'ions positifs qùi peuvent alors être déterminés de façon commode à l'aide d'un multiplicateur d'électrons à dynode continue. Application aux spectromètres de masse.The invention relates to negative ion detectors. It relates to a negative ion detector in which a transformation device receives the negative ions and creates a proportional amount of positive ions which can then be conveniently determined using a dynode electron multiplier. keep on going. Application to mass spectrometers.
