HPLC Method for Analysis of Chlorpyrifos (Dursban) on Newcrom B Column on Alltesta™ Chromatogramm

High Performance Liquid Chromatography (HPLC) Method for Analysis of Chlorpyrifos-methyl (Dursban)

Chlorpyrifos , also known as Dursban , is a highly toxic organophosphate with the chemical formula C9H11Cl3NO3PS . It works through interrupting the electrochemical processes in nerves. This leads to a build-up of acetylcholine, which leads to paralysis and eventual death.

Chlorpyrifos-methyl (Dursban) can be retained and analyzed using the Newcrom B stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with ammonium formate as a buffer. Detection is performed using UV.
