Carbofuran Separation on Primesep and Obelisc Mixed-Mode HPLC Columns


Carbofuran is one of the most acutely toxic insecticides used on field crops. It is banned in Europe, Canada, and as of 2009 was banned in the United States. The EURL (European Union Reference Laboratory), included carbofuran as a target pesticide for the EUPT-CF9 a proficiency test for cereals and feedingstuff that require muli-residue methods. Primesep B2 and Obelisc R were used to retain carbofuran 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 carbofuran and other phenoxy acids.
