PROBLEM TO BE SOLVED: To provide a method and an instrument for measuring mercury in coal combustion exhaust gas that will not be affected by coexisting components, and allowing precise and stable continuous measurement for a long period. SOLUTION: This method measures a reduced gas with the mercury in a sample reduced by a catalyst of inorganic material, having low reactivity to an acidic substance and reducing power for the mercury, and an oxidized gas with the measuring objective sample or the sample gas oxidized by an oxidation catalyst, using the coal combustion gas exhaust gas as the measuring objective sample, while being compared by an ultraviolet absorption analyzer.
