Читать книгу X-Ray Fluorescence Spectroscopy for Laboratory Applications - Michael Haschke, Jörg Flock - Страница 23

The laboratory sample, i.e. the sample material that is available in the laboratory, can have different forms: it can be compact, it can be small-particle size granule or powder-like, or it can be a paste or even a liquid. Increasingly, finished products have to be analyzed for quality assurance or fault identification purposes. As far as possible, they should not be modified for the analysis. Knowing the sample material, important information about the sample matrix can be obtained for the evaluation, such as information about non-measurable light elements.
