It includes procedures for internal and external QA/QC to ensure accuracy. The EPA's protocol for trace metal analysis using atomic absorption spectroscopy involves calibration with a method blank and three standards. Calibration is verified through ICV and ICB samples, needing results within ??10% accuracy.

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.
