ABSTRACT:
A method and apparatus for detecting the presence of a predetermined hydrocarbon vapour of a predetermined concentration in a monitored area by: exposing gas in or from the monitored area to radiation from a Xenon flashlamp which includes ultraviolet radiation of a predetermined ultraviolet spectral range and infrared radiation of a predetermined infrared spectral range; detecting the radiation after having passed through the gas; and comparing the detected radiation with a reference of predetermined attenuation characteristics of the hydrocarbon vapour and concentration in the respective ultraviolet and infrared spectral range.
