but making an accurate analysis of supply sources and grades of material is required. Knowing which supplier consistently provides a particular grade of material demonstrates a supplier’s reliability and a classification is possible: material suppliers can be ranked A, B or C, and purchasing costs are reduced. A sampling of materials during incoming inspection will give approximate values, but in order to achieve a robust classification with regard to delivered quality and purity, it is necessary to perform a comprehensive examination of the material. Ideally, a complete examination of the materials should be performed when the material is received.
Using a detailed analysis and the knowledge of who can provide that quality at what price, the optimization of margins is ultimately possible. Previously, the method for evaluating the degree of purity was by using a microscope or scanning electron microscope (SEM -EDX ). This method required a significant effort, was costly, and was time consuming, allowing for only partial sample reviews. But now, Bruker Elemental offers a tool to expedite the process. The Q8 MAGELLAN can give information about the purity level and the oxygen content of a material, in addition to determining its chemical composition. The review of the optical spark emission spectrometry can be done along with the usual element analysis. The time required is negligible (a few seconds), sample preparation is very simple, and the evaluation can be performed on the same equipment.
