[About mass-spectroscopy of aflatoxines (author's transl)]

The mass-spectroscopical identification of aflatoxines in the eluant after thin-layer-chromatographical seperation represents a problem at amounts of less than 50 ng normally found in foods. Therefore it was necessary to investigate the factors influencing the identification. Among others, influences of plate material and the eluant were found. Based on the results with pure aflatoxines ideas were developed on their possible reactions.
