FIELD: instrumentation.
SUBSTANCE: invention relates to the quantitative analysis of samples by method of laser-induced plasma. The system for classification of the movable materials in real time includes generator of laser pulses made with possibility to generate at least the first and the second laser pulses, that act on the same place on the movable materials, at that the first and the second laser pulses have time interval up to 10 mcs, and absorption detector made with possibility to generate the spectrum of absorption at the place of action within time interval of detection equal up to 20 ns, after second laser pulse.
EFFECT: invention increases classification efficiency.
