ABSTRACT:
A test vial for the detection of gas components in air, containing a packing changing along the longitudinal axis of the test vial is improved in such a manner that, at a constant flow resistance, a sensitivity for the hazardous substance to be detected is obtained, which varies along the test vial. The provision is made that the packing consists of a combination of applied indicator and carrier substance at ratios varying along the longitudinal axis.
