PROBLEM TO BE SOLVED: To provide an analyzer which can analyze organic substances and inorganic substances in a short time while suppressing generated amount of waste liquid. SOLUTION: This analyzer is provided with a liquid adding device 21 for adding a liquid such as water, an alcoholic organic solvent, an aliphatic organic solvent or the like to a sample 1, a wavelength adjuster 13 for irradiating the sample 1 with a first or a second wavelength laser beams 101a, or 101b, a heating lamp 22 for drying the sample 1, photomultipliers 18a-18c each of which has a gate function of receiving a light 102 emitted from the sample 1 for only a predetermined time and converts the intensity of the light 102 to an electrial signal, integrators 19a-19c each for integrating sizes of the light 102 for every time based on signals from the photomultiplier 18a-18c, and a computing unit 20 for obtaining an amount of organic hazardous substances in the sample 1 based on signals from the integrators 19a and 19b and obtaining an amount of inorganic hazardous substances in the sample 1 based on signals from the integrator 19c.
