Terbufos Analysis on Primesep 100 and Obelisc R Columns

September 14, 2015

 

Terbufos is an organophosphate pesticide and nematocide used in the production of bananas, sugar beets, corn and grain. It is typically applied to the seed or while planting, controlling many insects, wireworms, seedcorn maggots, white grubs, and corn rootworm larva. Terbufos is extremely toxic to workers exposed to concentrated granules. Two mixed-mode HPLC columns were used to separate terbufos with unique selectivity. Primesep 100 is a reverse-phase HPLC column that contains embedded acidic ion-pairing groups. Obelisc R retains compounds with embedded hydrophobic chains and multiple ion-pairing groups. Method can be used to retain and separate dozens of pesticides and is LC/MS compatible.

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 100

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.

Terbufos Analysis on Obelisc R HPLC Column

August 24, 2015

 

Terbufos is an extremely toxic organophosphate insecticide and nametacide. Obelisc R was used to retain terbufos and separate it from impurities. 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 terbufos and other organophosphate insecticides.

Condition 

Column Obelisc R, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN – 50%
Buffer AmFm pH 3.0- 40 mM
Flow Rate 1.0 ml/min
Detection UV, 250 nm
