Dicamba is an organochloride derivative of benzoic acid. It is used as a non-specific herbicide that is usually used on non-crop plants. Dicamba is moderately toxic to humans, and both persistent and mobile in soils. The EURL (European Union Reference Laboratory) tested dicamba in an analysis of acidic pesticides. Primesep 100 and Obelisc R were used to separate dicamba with unique separation. Method is LC/MS compatible

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 optionsThe 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.
