HPLC Diazinon Analysis on Primesep 100 column
September 14, 2015
Diazinon is a thiophosphoric acid ester which was used to control cockroaches, fleas, and silverfish in residential buildings. Diazinon is considered to be toxic for vertebrates causing a number of observed symptoms such as convulsions, headaches, and vomiting. Diazinon was was outlawed for residential use in the U.S. in 2004, but can be used in agricultural industries. There is a lot of interest in analyzing diazinon: it was analyzed in an analysis of acidic compounds by the EURL (European Union Reference Library) using QuEChERS methodology. Primesep 100 and Obelisc R were used to separate diazinon with unique selectivity. Method is LC/MS compatible and can be replicated for dozens of pesticides.

HPLC Separation of Diazinon on Obelisc and Primesep Mixed-Mode Columns
August 24, 2015
Diazinon is a nonsystemic organophosphate insecticide developed in the early 1950’s. It was heavily used as an all-purpose indoor/outdoor home pesticide, but was banned for home use in 2004. The thiophosphoric ester in diazinon can form toxic phosphine gases and phophorus oxides. The EURL (European Union Reference Laboratory), included diazinon 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 diazinon, other organophosphate insecticides, and dozens of other pesticides.

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.
