ABSTRACT:
A highly sensitive test tube according to the invention increases the sensitivity of detection of a component in a gas substantially and thus enlarges the area of use of the test tube. It possesses a reagent strip impregnated according to the gas to be detected, which strip is held by a granular fill material between holding elements. The test gas, conveyed by a pump through the test tube, from which test gas the gas to be detected is removed at the reagent strip, is continually moved through the granular fill material and thoroughly mixed, so that the actual continually decreasing concentration of the gas component is available at the reagent strip. Upon complete removal of this gas component by reaction with the reagent strip, the concentration can then be read at the reagent strip. The narrow reagent strip, which takes up the entire gas component, evidences even small admixtures.
