Sample preparation

A careful sample preparation is essential for analysis


The basis of sample preparation for further analysis is often enrichment of the element of interest and separation from the sample matrix. Different techniques are used for separation and isolation of the relevant element(s) so that matrix effects do not influence the measurement. If only a very small amount of the relevant element is available, different techniques for enrichment (concentration) are applied. Common methods include drying, precipitation and evaporation, pyrolysis, extraction and digestion.
