PROBLEM TO BE SOLVED: To enhance analyzing sensitivity and analysis accuracy, regardless of the presence of a coexistent substance, by making a target element rapidly convert to a chemical substance stable in a high density and high-concentration state at a low temperature to evaporate the same, regardless of the difference in evaporation behavior and suppressing the lowering of loss and transfer efficiency. SOLUTION: An ammonium halide is added to a sample (a solid-phase metal, a nonmetal or metal solution or a nonmetal solution) to heat the sample and the sample is converted to a chloride by the chemical reaction with a halogen produced by the sublimation pyrolysis accompanied by this heating to be evaporated/volatilized, while the evaporated/volatilized chloride gas is introduced into a chemical flame of AAS or plasma 20 of ICP through a transfer pipeline, and the absorbance or spectral intensity thereof is measured to quantify an element.
