HPLC Analysis of MCPA on Primesep and Obelisc Mixed-Mode Columns
   
MCPA (4-Chloro-2-methylphenoxy)acetic acid) was synthesized to control broad-leaf weeds such as thistle and dock. MCPA forms complexes with metal ions and increase their bioavailability. A single residue method was developed and used by the EURL (European Union Reference Laboratory) for acidic pesticides. MCPA was separated by both Obelisc R and Primesep 100. Primesep 100 is a reverse-phase column with embedded acidic ion-pairing groups while Obelisc R is a mixed-mode column with separates using ionic groups and a long hydrophobic chain. Methods are LC/MS compatible and able to be used with many pesticides.

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.
