Zusammenfassung:	Concentration measurements of gaseous components are possible by means of a sampling method, in which a measuring space of known volume is brought to the concentration level to be measured via a connecting means having a high transfer resistance, after which the gaseous component is rapidly removed from the measuring space. Removal of the gaseous component is effected by means of a partition, forming part of a wall section of the measuring space, in which ionic conduction takes place. The required charge, which is applied to the partition, is a measure of the concentration to be determined.
