HPLC Separation of Triadimefon on Obelisc and Primesep Columns

 

Triadimefon is a fungicide made up of a chlorophenol and a triazole. It is used on tropical fruit crops such as pineapple and banana. Primesep B2 and Obelisc R were used to retain triadimefon and separate it from impurities. Primesep B2 contains embedded basic ion-pairing groups and Obelisc R contains embedded ionic and hydrophobic groups which can assist in fine tuning separations. Method is LC/MS compatible and can be used as a general approach for analyzing triadimefon and dozens of other pesticides.
