Abstract

A non-dispersive gas analyzer comprising a light source, having light that shines through a measuring cuvette containing a measuring gas to be analyzed onto a non selective detector having a downstream evaluation unit, wherein a multi-component gas analysis is made possible using in a simple manner in that the light source is a flash discharge lamp and the evaluation unit is configured to evaluate the temporal pulse curves of the flash shining onto the detector such that it is possible to take advantage of the property of flash discharge lamps in that the emitted wavelength components vary over the duration of the flash.
