This application note describes a method for the analysis of volatile organic compounds (VOCs) in water using static headspace-GC/MS, including method optimization, sample preparation, and analytical method.
This document describes a static headspace (SHS) method optimized for the determination of volatile organic compounds (VOCs) in water. The method utilizes an Agilent 7890A GC coupled with a 5975C MSD equipped with triple axis detection to achieve purge and trap sensitivities while maintaining the robustness of static headspace.
| Sample Volume | 10-mL water samples |
|---|---|
| Vial Type | 20-mL headspace vial |
