Grinding samples has many benefits for sample preparation since it increases homogeneity, increases surface area and decreases particle size which can improve extraction efficiency. Some of the negatives regarding grinding samples are: potential contamination, increase in moisture, evaporation, loss or alteration of volatile …
The process includes grinding a sample into a fine powder, ideally to a grain size of <75um, mixing it with a binding /grinding aid and then pressing the mixture in a die at between 20 and 30T to produce a homogeneous sample pellet. The binding /grinding aid is usually a cellulose wax mixture and combines with the sample in a proportion of 20% ...

High-quality sample preparation is the key to achieving consistent and reliable analytical results. Powders are ideal for samples that crumble or ablate after pressing. They blend quickly and completely with samples to form XRF (x-ray fluorescence) sample disks. Tablets are an efficient way to add binder to XRF sample disks.

Grinding should be carried out in such a way as to ensure that no chamfers are made. In the case of the same amount of grinding, try to grind more and polish less. The principle of the two is different, grinding is the abrasive grain on the surface of the specimen, resulting in plough furrows, the difference in the soft and hard materials is small.
