Determination of major and minor elements in HF-digested soil samples
26 Nov 2020The accurate elemental analysis of soil and rock samples can depend on reliable and reproducible sample preparation methods. If silicate-based minerals are likely to be present in the samples, laboratories must use hydrofluoric (HF) acid during sample preparation to ensure complete sample dissolution. Regulated methods, such as US EPA 3052, require the use of HF to achieve total sample decomposition.
