Abstract

An organic substance analyzer, which comprises a irradiating unit for irradiating a specimen containing organic substances with an electron beam, a spectrum detecting unit for detecting spectrum of fluorescent light emitted from said specimen, a storage unit for storing a shape of a reference spectrum of fluorescent light of each specific type of organic substance when the electron beam is irradiated on said specific type of organic substance, and a searching unit for classification and identifying organic substances in the specimen by comparing the shape of said stored reference spectrum with that of said detected spectrum, whereby the electron beam having higher energy than light is irradiated the specimen for analysis, fluorescent light with spectrum in wider range is emitted from the specimen even in ultraviolet range, and organic substances in the specimen are discriminated and identified by comparing shapes of the measured spectral pattern obtained from the fluorescent light with a reference spectral pattern stored in memory in advance.
