Expert sample preparation steps such as crushing, grinding, sieving and remelting are used to homogenize the materials for laboratory tests. Each homogenization step is followed by a dividing step. Finally, the laboratory sample must be finely prepared to a final grain size that meets the requirements of the analysis.

Sample digestion for inorganic and organic samples is also an important sample preparation step. The digestion techniques must be adapted to both the material and the analytical question.

We use the following methods:

• Acid/melt digestion

• Microwave digestion,

• High-pressure digestion,

• Total digestion

• Enrichment methods
