PROBLEM TO BE SOLVED: To obtain an element analyzer capable of detecting many kinds of elements on-line for a real time regardless of a solid, liquid or gaseous sample form without requiring a complicated pretreatment process to determine them. SOLUTION: An element analyzer is equipped with a control device l outputting a control signal optimally holding the wavelength and output of laser beam and laser beam irradiating timing, a plurality of pulse laser devices 3a, 3b, 3c,...3n oscillating laser pulses corresponding to a given command, a synthesizer 4 for synthesizing laser beams for irradiating a sample, an analytical cell 6 having a laser condensing lens 5 for condensing laser beam to irradiate the sample and a fluorescence condensing lens 7 condensing the emitted light from plasma and a fluorometric device 8 for detecting the light having an inherent wavelength of an element to be measured.
