Abstract

The interconnection between, and evolution of, manufacturing trends, raw materials, XRF Instrumentation, XRF software capabilities, XRF Standard Reference Materials, and ASTM Standard Test Method for Chemical Analysis of Hydraulic Cement (C114), Rapid Method Qualification, is followed to show why certain XRF specimen preparation methods and inter-element correction methods were adequate at one time, but may not be adequate any longer, depending on many different variables unique to each plant location and business model. All of the above variables have changed over time, and the reasons why they have changed, and where they are going is explained. The theoretical basis for methods used during certain time frames is explained, and illustrated by example. From the trends observed in the variables previously listed, a conclusion about the direction of the modern cement laboratory in the near future is proposed.
