Abstract

Six brass alloys were tested using laser-induced breakdown spectroscopy (LIBS) to measure the optimal spectral wavelength of Cu and to determine the optimum system configurations for alloy measurements. The accuracy of the calibration curve was improved by a linear correlation for interference by the other elements and an exponential relationship for self-absorption. Multivariate regression method was used to compensate for the matrix effects. Results show a very satisfying improvement using the multivariate analysis method with the coefficient of determination of the optimized calibration curve improved from 0.953 8 to 0.999 8.
