This document describes the use of a 3mm diameter ZORBAX Low-Volume Column for analysis of pesticides in drinking water. 28 pesticides are separated with good resolution and peak shape in a single run using simple mobile phases.
A variety of pesticides are present in surface water at very low concentrations, requiring reliable analysis methods. High-Performance Liquid Chromatography (HPLC) with diode-array detection is an excellent tool for this purpose.
The document details a specific method developed by Dr. rer.nat. Claus Schlett that separates 28 pesticides in a single run using simple mobile phases and ZORBAX SB-C18 columns.
Substances can be detected in concentrations less than 0.1 mg/L.
The gradient elution runs for a total of 72 minutes.
Twenty-eight pesticides are separated with good resolution in a single run.
