HPLC Separation of Folpet on Obelisc and Primesep Mixed-Mode Columns


Folpet is a nonsystemic fungicide which is used to prevent apple scab, cherry leaf spot, rose black spot, and rose mildew. A method for folpet was provided by the EURL-SRM, a proficiency test for sigle residue methods developed by the European Union Reference Laboratory. Folpet was retained and separated from impurities with Obelisc R and Primesep B2 columns. 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 can be used for dozens of other pesticides and is LC/MS compatible.
