  • Process and apparatus for measuring the concentration of a molecule of selective spectrum in a sample substance
    Patent number: 4178102
    Abstract: A method and apparatus are described for measuring the concentration of a molecule of selective spectrum in a sample substance in which errors from spurious light signals due to diffused light or from spurious fluorescent or phosphorescent light due to traces of other molecules in the sample substance are eliminated. The invention subjects the sample substance to light of a first wavelength in the absorption spectrum of the molecule to be measured and obtains a signal representative of light emission from the molecule with the spurious light signals superimposed thereon.
