Background

Clays have many uses, from pottery, ceramics and porcelain fixtures, to coated paper, cosmetics and building materials such as cement and bricks. Accurate characterization and quality control of the minerals and oxides are important to establish confidence that the clays have the proper chemical composition and physical properties for their intended use. A rapid, reliable, yet cost-effective analytical technique is required to determine oxide content during mining and processing of the clay, as well as for quality assurance and quality control during production of clay products. Rigaku offers the NEX QC+ analyzer to meet these QA/QC challenges. The NEX QC+ analyzer utilizes direct excitation EDXRF to provide a simple and robust analysis method ideal for non-technical at-line operators and lab personnel alike.
