Method of analyzing inorganic phosphorus in organic material and apparatus therefor

摘要

A method of analyzing for red phosphorus contained in an organic material, the method comprising the steps of: pyrolyzing a sample composed of an organic material by heating the sample to a temperature equal to or higher than the sublimation temperature of red phosphorus to gasify the sample; separating the pyrolyzed sample to fractions by gas chromatography (GC); and detecting a fraction of a retention time corresponding to red phosphorus, wherein the step of detecting is performed with a mass spectrometer (MS).
