Abstract
It has been shown by residue analysis for ethylene thiourea in plant crops using gel and high performance liquid chromatography that residues are considerably reduced when the samples are macerated for extraction, and the plant juices are liberated. Consequently, residue values which are too low are obtained. Therefore, it is recommended, that only surface rinsing should be used. In Untersuchungen zur Rückstandsanalytik von Äthylenthioharnstoff (ETU) in pflanzlichen Erntegütern auf gel- und hochdruck-flüssigkeitschromatographi-schem Wege wurde gezeigt, daß die bei der Zerkleinerung des Probenguts für die Extraktion freigesetzten Pflanzensäfte die ursprünglichen ETU-Gehalte erheblich reduzieren und daß damit ein zu geringer Rückstandswert erhalten wird. Es wird daher ausschließlich Oberflächen-Abspülung empfohlen.This publication has 20 references indexed in Scilit:
