HPLC Separation of Folpet on Zodiac HST B2 Column

Folpet is a nonsystemic fungicide used to prevent plant diseases such as apple scab, cherry leaf spot, rose black spot, and rose mildew. A method for analyzing Folpet was developed by the EURL-SRM, a proficiency testing program created by the European Union Reference Laboratory for single-residue methods.

Folpet was effectively retained and separated from impurities using the Zodiac HST B2 column. Zodiac HST B2 features embedded basic ion-pairing groups, which enhance selectivity and resolution for complex pesticide mixtures. The method is LC/MS compatible and can be applied to the analysis of dozens of other pesticides.
