Department of Mathematics and Natural Sciences, BRAC University Carat values ED-XRF Impurities Libs This conference paper was presented in the 3rd International Conference on Photonics, Optics and Laser Technology, PHOTOPTICS 2015; Berlin; Germany; 12 March 2015 through 14 March 2015 [© 2015 SciTePress] The conference paper's definite version is available at: 10.5220/0005249300410046 Laser induced breakdown spectroscopy (LIBS) and low energy dispersive X-ray fluorescence (ED-XRF) spectrometer, were used to determine the line intensity and concentration ratios of the major impurities (Cu and Ag) with respect to Au in gold ornaments with different caratage. Calibration curves were drawn with the data sets, obtained from LIBS and XRF, and from these calibration curves the unknown caratage of gold ornaments were obtained by using the line intensity of elements determined by LIBS. We have demonstrated the accuracy of this method by comparing the result with the carat value obtained by typical XRF method. This is yet another novel application of LIBS as a versatile analytic technique. Published 2017-04-09T05:20:57Z 2017-04-09T05:20:57Z 2015 Conference paper Haider, A. F. M.
