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. KATANAX K1全自动电热融熔机 KATANAX K2全自动电热融熔机
