| Abstract: | Laser-induced plasma was generated by focusing laser radiation from a Nd:YAG laser on the alloy samples. The plasma emission was collected by a multi-channel grating spectrometer and finally detected by CCD detectors. The calibration curves were established by different characteristic lines of constitute elements, and then the quantitative analysis of Fe,Cu and Si in aluminum alloys was achieved. The relative errors of measurement were smaller than 10%, and the detection limit could reach 10-4 magnitude. The results demonstrated that the quantitative analysis of multi-element alloys could be achieved in a short time by the LIBS technique. |
