The utility model relates to a portable laser-induced breakdown spectroscopy analyzer. The analyzer comprises a solid-state laser, an optical path unit and a data processing unit, wherein the optical path unit comprises a dichroscope, a first focusing lens, a second focusing lens, an optical fiber and a multi-channel spectrograph; laser emitted by the solid-state laser is projected to a sample through the dichroscope and the first focusing lens sequentially; a radiation signal emitted by the sample sequentially enters an entrance end of a beam-splitting optical fiber through the first focusing lens, the dichroscope and the second focusing lens and enters the multi-channel spectrograph from multiple optical fiber branches; the data processing unit comprises a data acquisition unit connected with the spectrograph and a processor connected with the data acquisition unit. The radiation signal is generated through a laser-induced sample and is collected and analyzed through the optical path unit and the data processing unit, and then the elementary composition and concentration of the sample are obtained. |
