Application description
Dursban or Chlorpyrifos (CPS) is an organophosphate pesticide. It is used in crops, animals, and buildings. CPS is moderately hazardous to humans. Dursban is hydrophobic and basic in nature. It is retained on Coresep 100 mixed-mode column by reversed-phase and cation-exchange mechanism. Chlorpyrifos is well retained with perfect peak shape. Retention time is controlled by the amount of ACN, buffer pH and buffer concentration. This method is compatible with LC/Ms and does not require ion-pairing reagent. The column and method can be used for analysis of multiple pesticides, herbicides, insecticides, and other agricultural products.
