Dichlorvos Separation on Obelisc and Primesep Mixed-Mode Columns

August 24, 2015

 

Dichlorvos is an insecticide used in household products, pet products and used in industry to protect food stores. Effective against caterpillars, aphids, spider mites, thripes and many types of flies. Dichlorvos is prevalent in many urban waterways and can be acutely and chronically toxic to humans. The EURL included dichlorvos as a target pesticide for the EUPT-CF9. Primesep B2 and Obelisc R were used to retain dichlorvos and separate it from impurities. Primesep B2 contains embedded basic ion-pairing groups while Obelisc R contains embedded ionic and hydrophobic groups which can assist in fine tuning separations. Method is LC/MS compatible and can be used with dozens of pesticides also as a general approach for analyzing dichlorvos and other organophosphate insecticides.

Application Column

Obelisc R

SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.

Primesep B2

The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers. Inquire about our specially-tailored custom LC-phases for specific separations.
