X-ray Fluorescence Analysis of Cements 采用加拿大Katanax熔融机 The combination of a borate fusion and "Delta-Coefficient'' corrections for matrix effects is shown to yield a method for the analysis of cements in which high accuracy, rapidity, and slmpllcity are compatible. The features of the method are: (a) Counting statistics is nearly the only source of errors. (b) Weighing of flux and sample are nearly the only manipulations. (c) One standard only is required. (d) When cement composition is rather constant, the method described can be shortened significantly. The analysis of the six major elements In NBS-633-639 cements was performed with an average accuracy of 0.07 YO.
