As pure as possivle
Even if size reduction is carried out under ideal conditions, the mechanical stress which the sample material exerts on the surface of the grinding tool causes abrasion. However, it is possible to minimize this effect by selecting suitable mills and grinding tools. If the sample material needs to be ground to sizes below 100 microns, strong mechanical forces are required which increase abrasion.
The preparation of samples of solid substances for spectroscopic analysis
X-ray fluorescence spectrometry is one of the most versatile multi-element methods of chemical analysis. The technique is based on excitation of fluorescent radiation from a sample by bombarding it with high energy X-ray quanta and subsequent study of the characteristic X-ray radiation emitted by its elements.
