Method of atomic absorption measuring
Description
A method of measuring atomic absorption has been proposed which makes it possible to increase accuracy and sensitivity of measuring small values of optical density. Two intensity-equal fluxes are formed, one of which is a resonance flux and the second is a flux of comparison. The fluxes pass successively through the atomic vapours of the sample with a repetition frequency about 20-times less than carrier frequency. The measured depth of modulation is taken as a measure of atomic absorption
