This document describes the HPLC analysis method of bendiocarb and metabolite
This document details a High-Performance Liquid Chromatography (HPLC) method for the analysis of the insecticide bendiocarb and its metabolite. The method utilizes a Hypersil ODS C18 column with a mobile phase of water and acetonitrile, detected at 212 nm using a diode array detector. The procedure covers extraction from soil and water, as well as separation and detection parameters.
| Column | 100 x 2.1-mm Hypersil ODS C18, 5 ym |
|---|---|
| Mobile phase | Water—acetonitrile (65:35 isocratic mixture) |
| Flow rate | 0.36 ml/min |
| Temperature | 40 °C |
| Detection wavelength | 212 nm (16 nm bandwidth) |
| Detection limit | 4 yg/! |
Samples can be extracted from soil using Soxhlet equipment or by ultrasonic treatment in solution, and from water using liquid—solid or liquid-liquid techniques.
The detection limit is 4 yg/! without sample enrichment.
