The reactive gas is introduced in excess. The quantity of light produced is proportional to the sample flow rate and the concentration of the measured substance in the sample under specified temperature and pressure conditions. The filter limits the wavelength to the region of interest and helps to eliminate interferences.","links":[{"term":"filter","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/F02384"},{"term":"optical filter","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/O04307"},{"term":"reagent","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/R05190"},{"term":"wavelength","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/W06659"}],"sources":["PAC, 1990, 62, 2167.
