The term Geochemical Analysis is used today to describe a multi-element analysis where a large suite of elements are determined to an intermediate level of accuracy. The use of this type of analysis is very dependent on the digestion used and the intended application of the data, i.e. “fitness for purpose”. Geochemical methods were designed to be a low cost screen for many elements with low detection limits through minimal dilution before analysis. Matrix effects from the highly concentrated solutions also effects accuracy. Monitoring standards are also perhaps not available for all elements in the package. Despite all this, the accuracy will typically be +/- 5-20% if the analyte is at least 10 times the stated detection limit.
