MULTICOMPONENT PROCESS-ANALYSIS SYSTEM

摘要

A multicomponent process-analysis system for gases or liquids quantitatively determines the radiation absorbed by the gases or liquids in the UV to IR spectral range, the gases or liquids being irradiated with absorbable radiation which is split up optically by the radiation-transmitting gases or liquids, and individual spectral ranges are separately recorded by a detector device. The object of the invention is to design the above multicomponent process-analysis system in such a way that the emission or absorption spectrum of a mixture of many substances can be recorded simultaneously in the UV to IR spectral range, thereby making an on-line determination of the concentration of a plurality of components possible. The achievement is characterised in that the spectral splitting is carried out by means of dispersing optics and that a detector simultaneously measures these spectral components.
