Description
technical field [0001] The invention relates to the field of automatic sample preparation, in particular to an automatic sample preparation system for a laser-induced breakdown spectrometer. Background technique [0002] Laser-induced breakdown spectroscopy (LIBS) technology is a new method developed in recent years to detect the composition of substances. This method uses a high-power-density laser to irradiate the sample, induces plasma, and collects the plasma emission. Spectra to obtain the type and content information of the elements in the sample. LIBS does not require complex sample pretreatment, the equipment used is relatively simple, and the detection cost is low. It can complete real-time, fast, non-destructive online analysis without causing secondary pollution. It is a method to directly test the elemental composition of samples. [0003] When using laser-induced breakdown spectroscopy to detect the composition of substances, although complex chemical pretreatm...
