Preparation of samples for analysis 0600-S2-CKR-PPA

The lecture aims to provide knowledge on how to collect a sample for analysis, average it and transform it into a form in which it can be analyzed using various methods and techniques.
The following processes will be discussed: dry and wet mineralization, digestion, dissolution, dilution and concentration. In addition, methods of isolating the analyte from the matrix will be presented. An integral part of the lecture will be a discussion of the types of contaminants, their sources and prevention of contamination. As an introduction to conducting individual analyses using various measurement techniques, the basic characteristics of each of them will also be discussed (including: range of determination, measurement possibilities, etc.). Another issue discussed during the lecture will be to familiarize the audience with the criteria for selecting a measurement method and technique.
The laboratory covers the most commonly used methods of preparing samples for analysis and the impact of the sample preparation process on the analysis result.
During the laboratory, students will perform:
1. Taking an analytical sample
2. Dry and wet mineralization
3. Sample digestion
4. Isolation of the analyte from the matrix (precipitation, filtration, centrifugation, extraction, distillation)
5. Sample purification and concentration
6. Preparation of bulk material samples for analysis (sieve analysis, LDPS)
