SPECTROSCOPIC ANALYSIS APPARATUS COMPRISING A MULTI-CHAMBER CUVETTE FOR FLUID OR GAS ANALYSIS AND CORRESPONDING METHOD

A spectroscopic analysis apparatus comprises a multi-chamber cuvette for fluid or gas analysis, wherein the multi-chamber cuvette comprises at least two measurement chambers into which fluid or gas can be introduced for analysis, wherein the at least two measurement chambers are optically separated from one another, wherein an illumination device is provided to generate light and to couple the light into the at least one first and second measurement chamber, and wherein a detection device is provided to measure an intensity of the light radiated by the fluid or gas in the first measurement chamber for a first wavelength and to generate a first measurement result and to measure an intensity of the light radiated by the fluid or gas in the second measurement chamber for a second wavelength and to generate a second measurement result, wherein the first wavelength and the second wavelength are different.
