An improved detection reaction for benzene in gas analysis with a gas detector tube formed of a carrier material impregnated with gold(III) oxide in a display layer.

Gas detector tube for determining benzene

A device and method in which the gas specimen to be investigated is exposed to one or more indicators for qualitative or quantitative detection of methylisothiocyanate, characterized in that at least one indicator is palladium sulfate.

Device and method for detecting methylsothiocyanate

A device for detecting sulfuryl fluoride, in which the gas specimen to be examined is subjected to pyrolysis with ensuing detection of a pyrolysis product, is to be improved for the sake of achieving a mobile, economical structure. To attain this object, in a preliminary tube () for pyrolysis, there is a chemical layer () of pyrophoric iron, and as an indicator system for the pyrolysis product, a test tube () for hydrogen fluoride is used.
