HPLC Analysis of Bentazon on Primesep and Obelisc Mixed-Mode Columns

September 8, 2015
Bentazon is a thiadiazine herbicide which is used to control the growth of specific plants. Some plants are not affected such as alfalfa, corn and peanuts. The EURL (European Union Reference Laboratory) included bentazon in an analysis of acidic pesticides using QuEChERS method. Primesep 100 and Obelisc R were used to retain and separate bentazon from impurities. Method is LC/MS compatible and developed to be used for many 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.

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. Inquire about our specially-tailored custom LC-phases for specific separations.
