Abstract

The invention relates to a multi-sensor laser system for the selective trace analysis of organic material, the multi-sensor system having at least one laser ion mobility spectrometer, an absorption spectrometer and a fluorescent measuring device. The system is characterized in that it is equipped with a device for the simultaneous generation of a common laser beam with different wavelengths and pulses for the simultaneous operation of the laser ion mobility spectrometer, the absorption spectrometer and the fluorescent measuring device. This avoids the disadvantages of the known solutions in prior art and provides an improved solution for the highly sensitive and highly selective trace analysis of organic material, in particular hazardous substances such as explosives and warfare agents in the air.
