Method and device for the quantitative gas analysis

摘要

The invention relates to a device and a method for the quantitative gas analysis in which the gas analysis of a sample atmosphere is implemented by means of a sensor device, a diffusion seal being produced between the sample atmosphere contained in a sample system and a measuring chamber and the gas analysis of the sample atmosphere which is diffused into the measuring chamber being implemented with the sensor device, the sensor head ( 5 ) being able to be coupled to the measuring adapter ( 4 ) and the radiation source ( 16 ) and the detector device ( 17 ) being fixed to the measuring chamber ( 9 ) in a defined orientation and the measuring radiation ( 24 ) emitted from the radiation source ( 16 ) traversing at least once through the measuring chamber ( 9 ) and being detected by the detector device ( 17 ) after leaving the measuring chamber ( 9 ).
