Abstract

1. A test tube for the quantitative measurement of minimal concentrations of gaseous components, comprising a reagent strip (11) impregnated with chemical reagents before which in the throughflow direction is arranged a gas-permeable flow-resistor element (6, 6a), characterized in that the latter is either : a) a fine-grained layer (6) of a chemically inert material which has as uniform as possible a granulometry, or b) a capillary tube (6a) inset with sealed rims in the test tube (1).
