Dicamba Analysis on Primesep and Obelisc Mixed-Mode HPLC Columns
 
Dicamba is a widely used herbicide. Dicamba mimics auxin, a plant growth hormone, increasing growth beyond the resource availability of the plant. The EURL (European Union Reference Laboratory) included a QuEChERS (Quick, Easy, Cheap, Rugged, and Safe) method for dicamba as a target pesticide for EUPT-SRM. Obelisc R and Primesep B2 were used to retain dicamba and separate it from impurities. Primesep B2 contains embedded basic ion-pairing groups while 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 dicamba, other auxin-like phenoxy acids, and dozens of other pesticides.

Retention of the Herbicide Dicamba on Mixed-Mode HPLC Columns
  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

HPLC Separation of Pesticides, Herbicides, Fungicides and Insecticides on Newcrom BH Column
Herbicides are used to control unwanted plants, they are also known as weedkillers. Insecticides are used to kill insects. Fungicides are used to kill parasitic fungi. Pesticide is a more generic term that includes herbicides, fungicides and insecticides in its definition. All are heavily used in agriculture. By using HPLC, many different pesticides can be separated and their retention characteristics controlled using the Newcrom BH mixed-mode column. It can be used with different organic media such as acetonitrile (ACN) or methanol (MeOH). By varying the concentration of organic modifier and using different buffers like sulfuric acid (H2SO4), ammonium formate (AmFm), or formic acid, separation of desired pesticides can be achieved.

Mobile Phase MeCN, MeOH
Buffer H2SO4, Formic acid, AmFm pH 3.0
Flow Rate 0.6 ml/min
