The colored and transparent glasses were glass standards used for calibration in ii-ray fluorescence spectrometry and exhibited a 0.15-3.5 absorbance range at 355 nn. Translation of the target (1 mm s(-1)) with respect to the laser beam was used over a length of 16 mm. The depths and widths of the corresponding patterns were not related to the absorbance of the samples. However, the analytical Line intensities were efficiently compensated for by using the Si(I) 251.611 nm line as an internal standard. The repeatability was therefore improved for Na, K, Ca, Mg, Sr, Ba, Zn, Pb, Al, Fe, and Sb, as well as the correlation coefficients of the regression and the centroid uncertainties of the calibration graph. Preliminary investigations were carried out to evaluate the acoustic signal emitted by the microplasma as external standardization. However, a negative correlation was found with the Line intensity signals under our operating conditions. ER -
