| titleOfInvention | The method and apparatus of trace metal element in direct-current discharge vaporization auxiliary laser induced breakdown spectroscopy detection water body |
| abstract | The invention discloses the apparatus and method of trace metal element in a kind of direct-current discharge vaporization auxiliary laser induced breakdown spectroscopy detection water body.Fluid sample is vaporized by HVDC electric discharge, the sample of vaporization is separated by separator, by in gas injection to graphite carrying tablet, graphite carrying tablet containing element to be measured produces plasma by pulse laser ablation induction and launches spectral signal, tested and analyzed eventually through spectrometer, so as to realize the measurement to the trace metal in water body.Using this method and its device, the efficiency of pulse laser ablation sample is greatly improved, and the spectral signal of detection obtains larger enhancing, improves detection sensitivity, the detection limit of metallic element is reduced, feasible method is provided for the metallic element in online efficient, quick detection water body. |
