This Application Note describes the use of Agilent Purge-and-Trap/Gas Chromatography/Mass Spectral Detection technology for the analysis of volatile organic compounds in water.
This document details the use of purge-and-trap sample concentration combined with gas chromatography and mass selective detection (GC/MSD) for analyzing volatile organic compounds (VOCs) in water samples. It highlights the system's ability to quantify compounds at concentrations as low as 0.1 ug/L (ppb). The text outlines the experimental setup, including specific instrumentation and conditions used for analyzing 60 common VOCs.
| Detection Limit | 0.1 ug/L (ppb) |
|---|---|
| Sample Size | 5-mL or 25-mL |
| Column | 20-m x 0.18-mm x 1.0-ym J&W DB-VRX |
| Software | Agilent EnviroQuant ChemStation |
Purge-and-trap sample concentration followed by gas chromatography with mass spectral detection.
Using 25-mL samples increases sensitivity by a factor of 5 compared to 5-mL samples.
