ABSTRACT:
A gas analysis apparatus employing partitions with ionic conduction which, instead of using a capillary opening or a semi-permeable membrane to fill a measuring space by means of a continuous diffusion process, employs the partition (8, 8a) which is used for rapidly emptying a measurement space (7, 7a) also for filling the measurement space up to the concentration to be measured. For this purpose a pumping current (i.sub.p) is replaced by a filling current (i.sub.v) of opposite polarity.
