ABSTRACT:
An analysis method and analysis apparatus involve analysis for a sulfur component using ultraviolet fluorescence capable of removing the interferential influence of NO with good efficiency and certainty to thereby measure a concentration of only sulfur components such as SO2and others even in continuous measurement over a long term with a high precision. An analysis method involves analysis for a sulfur component using ultraviolet fluorescence. A sample gas is illuminated with ultraviolet and fluorescence is emitted by the ultraviolet illumination and detected to measure concentrations of sulfur components including at least SO2in the sample gas. NO, which is an interferential component in the sample gas, is oxidized to nitrogen dioxide, followed by the illuminating of the sample gas with ultraviolet.
