Abstract

Ved en fremgangsmåte og en anordning for spektroskopisk I mengdebestemmelse av gasser (4) i gassblandinger anvendes i periodisk vekselvis monokromatisk lys (1) ved minst to I bølgelengder, idet lyset ved en av nevnte bølgelengder er ' karakteristisk og lyset ved minst en annen av disse bølge- ¦ lengder er ukarakteristisk for lystransmisjonen i den gass I hvis mengde skal bestemmes. Denne transmisjon frembringer I elektriske signaler hvis harmoniske andeler inneholder minst ien uliketalls Fourierfrekvens av en emisjonsperiode, og hvis i amplityde er proporsjonal med konsentrasjonen av den gass (4) I som skal bestemmes i gassblandingen samt forsvinne sammen med denne konsentrasjon.In a method and apparatus for spectroscopic determination of gases (4) in gas mixtures, periodic alternating monochromatic light (1) is used at least two I wavelengths, the light at one of said wavelengths being characteristic and the light at least one of these. wavelengths are uncharacteristic of the light transmission in the gas I whose quantity is to be determined. This transmission produces in electric signals whose harmonic proportions contain at least one odd Fourier frequency of an emission period, and if in amplitude is proportional to the concentration of the gas (4) I to be determined in the gas mixture and to disappear with this concentration.
