- W2390913529 abstract "In this paper,the feasibility of using calibration free-laser induced breakdown spectroscopy for quality inspection of gold jewelry was proved by using this method to analyze a series of gold alloy samples.The samples were induced by an Nd∶YAG pulse laser beam with a wavelength of 1 064 nm,and the atomic spectrum in the range of 200—760 nm was recorded by a fiber spectrometer with 4 CCD.Six standard gold alloy samples with the gold contents from 85.0% to 99.6% were used in the experiment.The laser induced breakdown spectra were gathered and the atomic and irons lines of elements Au,Cu,Ag in these spectra were chosen for calibration free analysis model.Saha-Boltzmann plots were obtained and content of these three elements was achieved for all samples.The relative error of the main element Au was less than 3%." @default.
