Agilent Low Level Measurement of Cadmium in Foods Application Note
This document outlines a procedure for determining cadmium concentrations in animal and plant tissues, including dairy products, grains, fruits, vegetables, and oil seeds. The method is suitable for cadmium concentrations in the range of 0.01-0.3 µg/g. The process involves digesting samples via wet ashing, complexing cadmium with ammonium pyrrolidine dithiocarbamate (APDC), and extracting it into di-isobutyl ketone (DIBK). The organic phase is then stripped with dilute nitric acid, and the resulting aqueous phase is analyzed using Graphite Furnace Atomic Absorption Spectroscopy (GFAAS).
