Abstract：In the present paper, the lead concentrations of samples including glass, soldering tin and so on were determined by LIBS based on a Nd∶YAG Q-switched pulse laser with wavelength 1 064 nm as an exciting source and CCD in common spectrograph as the detector. The pulse energy on the surface of samples is about 95 mJ and the pulse width is 12 ns. By the detection of different samples, the detection limit of lead in samples was found to be 0.007 4% and the maximum relative standard deviation of quantitative analysis was about 4.0% based on the LIBS system of the instruments all made in China. The quantitative analysis can be done in two or three minutes and will spend one minute finishing the process by software in the future. The results suggest that the accuracy of determination of lead meets the challenge of quantitative analysis and the CCD can displace the very expensive ICCD as detector. The feasibility and low cost of the method, which uses common spectrometer and CCD to realize the LIBS detection, is proved by the result and our investigation will be beneficial to the LIBS application.
