This application note demonstrates the performance of the VF-1701ms with EZ-Guard in the separation of pesticides.
This document describes the use of the Agilent J&W FactorFour VF-1701ms gas chromatography column equipped with an EZ-Guard integrated guard column for analyzing halogenated pesticides. The EZ-Guard design eliminates leakage and adsorption risks associated with traditional guard columns, thereby improving column lifetime and sensitivity. The VF-1701ms is noted as a common conformal column for pesticide analysis, and this note highlights its effectiveness with the EZ-Guard system for complex sample matrices.
