It has been previously shown that borate fusion using a M4 gas instrument and Wavelength Dispersive XRF (WDXRF) can comply with the analytical targets described in ASTM C 114 and ISO/DIS 29581-2 for cement analysis. As the demand for electric fusion devices increases in the cement industry, it is of interest to evaluate the performance of LeNeo and TheOx Advanced electric fusion instrument to access its capacity to comply with these analytical standard test methods using the same calibration strategy. This webinar presents the results of a calibration strategy that allows the analysis of chlorine (Cl) in cement materials using a borate fusion and WD-XRF method.
