| titleOfInvention | A kind of multi-gas mixed LIBS signal enhancement device and heavy metal detection method |
| abstract | The invention provides a multi-gas mixed LIBS signal enhancement device and a heavy metal detection method. The device includes: a solid pulse laser, an optical path system, a multi-gas mixed spherical gas chamber, a fiber collector, a spectrometer and a controller; the optical path system and the solid state The pulsed laser is connected, the multi-gas mixed spherical air chamber is set corresponding to the optical path system, the optical fiber collector is set corresponding to the multi-gas mixed spherical air chamber, the spectrometer is connected with the optical fiber collector, the controller is connected with the spectrometer and the solid pulse laser respectively, and the spectrometer is connected with the optical fiber. The optical signal received by the collector determines the laser-induced breakdown spectral information; the controller determines the LIBS spectral information according to the received laser-induced breakdown spectral information; the invention provides a uniform mixed environment atmosphere of multiple gases for laser ablation of the sample to be detected to generate plasma The ability to eliminate the detection needs, adjust the gas input and air ratio, adjust the pressure, enhance the LIBS spectral information and improve the accuracy of heavy metal content determination. |
