摘要：The invention relates to a colorimetric gas measuring device having a porous substrate accessible to the air sample to be investigated. The substrate includes a conversion zone which converts a component to be detected into a substance which leads to a coloration of an indicator in a detection zone. The gas measuring device makes possible a simple and inexpensive quantitative detection of chlorosilanes. For this purpose, the conversion zone includes silica gel and the detection zone includes a carrier impregnated with an acid indicator.
