Abstract
Ionization chamber for the chemical ionization of vapors of substances in ion-molecule reactions by means of ionizing primary particles and a reactance gas, having at least one inlet opening for feeding the reaction partners and at least one outlet opening for the reaction products formed in the chamber. As shown, the ionization chamber has an elongated shape. The inlet opening for the ionizing primary particles on the one hand, and the outlet opening for the reaction products on the other hand, are arranged in alignment in opposite end walls of the ionization chamber.
