Types of the samples. Sampling of gas, liquid and solid state materials, metals. Sampling for speciation analysis and for the analysis of environmental samples (air, waters, biological samples sediments and soils). Error sources of the sample preparation. Classic sample preparation methods (dissolving, decomposing, acidic flux, decomposition of organic compounds). Modern digestion methods (high temperature digestion with conventional heat transmission, microwave assisted digestion methods, dry ashing for decomposing organic (biological) samples. Aqueous reagents for dissolving or decomposing samples. Enrichment and separation methods. Sample preparation methods for speciation analysis.
