Abstract
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.
Claims20
A gas detector tube for detecting benzene, the detector tube comprising:
- a display layer which consists essentially of a carrier material impregnated with gold(III) oxide.
A process for detecting benzene in a gas sample, the process comprising the steps of:
- providing a gas detector tube with a display layer which consists essentially of a carrier material impregnated with gold(III) oxide;
- and
- passing the gas sample into the gas detector tube such that the gas sample is reacted with the carrier material impregnated with gold(III) oxide.
