This article describes the method and conditions for pesticide analysis by GC/ECD using Agilent J&W FactorFour VF-5 Pesticides and VF-1701 Pesticides columns. The method effectively separates EPA 8081 pesticides and provides peak identification data for VF-1701 Pesticides and VF-5 Pesticides columns.
This document is an application note from Agilent Technologies detailing the analysis of EPA 8081 pesticide standards using Gas Chromatography with Electron Capture Detection (GC-ECD). It specifically evaluates the performance of two new generation FactorFour columns: the VF-5 Pesticides and the VF-1701 Pesticides.
| Technique | GC-ECD |
|---|---|
| Column Type | Fused silica |
| Column Dimensions | 30 m x 0.25 mm df = 0.25 ym |
| Part Number VF-5 | CP9070 |
| Part Number VF-1701 | CP9074 |
| Injector Temperature | 250 °C |
| Detector Temperature | 275 °C |
| Sample Size | 0.5 yL |
| Sample Concentration | 200 ng/mL |
The analysis uses Agilent J&W FactorFour VF-5 Pesticides and VF-1701 Pesticides columns.
The temperature starts at 59 °C (hold 30 sec), ramps to 150 °C @ 15 °C per min, then to 275 °C @ 4°C per min.
