It covers direct precipitation and the method of separating analytes already in particulate forms using filtration and extraction techniques. Filtration uses different filters based on the particle size, while extraction involves separating analytes from a matrix using a suitable solvent.

It emphasizes the importance of a well-structured sampling plan, including choices about sample types (e.g., random, systematic), collection methods (e.g., grab, composite), and considerations of the population's nature (homogeneous or heterogeneous).
