Participating laboratories could use Photochemical Derivatization or electrochemical derivatization.  The sample clean-up was performed using Immunoaffinity clean-up columns.

Pickering has many great tools for the analysis of Aflatoxins, including the UVE Photochemical Reactor, our Pinnacle PCX, immunoaffinity clean-up columns, HPLC columns, and column handling equipment such as the FREESTYLE SPE, AcceCLEAN, and EluVac.
