HPLC Separation of Phosphamidon on Mixed-Mode Columns

2015-09-14

 

Phosphamidon is an organophosphate insecticide highly toxic to mammals and classified by the World Health Organization to be extremely hazardous (Ia), with an oral lethal dose of less than 5mg/kg of bodyweight. The EURL (European Union Reference Laboratory) included phosphamidon as a target pesticide for the EUPT-CF9. Primesep 100 and Obelisc R were used to retain phosphamidon and separate it from impurities. Primesep 100 contains embedded acidic 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 phosphamidon, other organophosphate insecticides, and dozens of other pesticides.

SIELC Technologies usually develops more than one method for each compound. Therefore, this particular method may not be the best available method from our portfolio for your specific application. Before you decide to implement this method in your research, please send us an email to research@sielc.com so we can ensure you get optimal results for your compound/s of interest.

Obelisc R

SIELC has developed the mixed-mode Obelisc™ columns to be the first commercially available columns with Liquid Separation Cell technology (LiSC™). This cost effective duo can replace multiple HPLC columns such as 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.

Select options

Primesep 100

The Primesep family of mixed-mode columns offer a wide variety of stationary phases with an unprecedented selectivity in the separation of a broad array of chemical compounds and in multiple applications. Corresponding Primesep guard columns are available with all stationary phases and do not require holders. SIELC offers a method development service which is available for all customers. Ask about our special custom LC-phases tailored for specific separations.

Phosphamidon Analysis Using Obelisc and Primesep Mixed-Mode HPLC Columns

2015-08-24

 

Phosphamidon is an organophosphate insecticide commercially available as 70% Z-isomer and 30% E-isomer. It is highly toxic to mammals, and is classified by the World Health Organization to be extremely hazardous (Ia), with an oral lethal dose of less than 5mg/kg of bodyweight. The EURL included phosphamidon as a target pesticide for the EUPT-CF9. Primesep B2 and Obelisc R were used to retain phosphamidon 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 phosphamidon, other organophosphate insecticides, and dozens of other pesticides.
