In a direct precipitation gravimetric analysis, for example, we convert a soluble analyte into an insoluble form that precipitates from solution. In some situations, however, the analyte is already present as in a particulate form that is easy to separate from its liquid, gas, or solid matrix.

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.
