Methods for metals analysis of solid samples can be classified in two categories: direct and combined analytical methods.

Direct Analytical Method: Solid Sample → Mechanical Sample Preparation (Grinding, Sieving, Weighting, Pressing, Polishing, etc.) → Multi-element Analysis by XRF.

Combined analytical methods: Solid Sample→ Mechanical Sample Preparation (Grinding, Drying, Weighing) → Decomposition → Filtration, Dilution → Multi-element analysis (AAS, GFAAS, ICP-MS).
