Plane grinding with diamond is the best choice to ensure flat samples from the very beginning of the preparation. Fine grinding with either MD-Largo or MD-Allegro will provide the best possible planeness. To avoid relief, preparation time and the type of polishing cloth used are the most important parameters.

producing a representative sample by crushing, dividing and fine grinding before elemental analysis. Correct preparation and homogenisation of the sample is an indispensible prerequisite in obtaining reproducible and reliable analysis results with a minimum standard deviation.

Before the actual analysis, the sample materials need to be homogenized and reduced to a sufficiently small particle size. The Knife Mill GRINDOMIX GM 200 sets standards in food sample preparation: The cutting effect produced by the steel blades results in the perfect homogenization of samples with high water, oil, sugar or fat content.

Jaw Crushers are ideal for pre-crushing of very hard, hard, medium-hard, brittle, tough and temperature-sensitive materials. The sample is crushed under high pressure between one fixed and one movable crushing jaw. The grinding parts are available in various steel types, hardmetal tungsten carbide and zirconium oxide to prevent undesired abrasion.

Modification of the sample material through cutting, drilling or grinding using various saws or drilling tools are carried out to adjust the sample material for further processing or analysis, e.g. for thin section puck production, epoxy mount finishing, …
