Fully automated on-line headspace monitoring of VOCs

This study demonstrates a fully automated GC analysis of volatile organic compounds (VOCs) in the headspace of waste effluent using a flow-through cell with a sample preparation robot, and detection by FID and/or TOF MS. The use of these two detection techniques enables robust on-line quantitation of target compounds, as well as confident identification of unknowns and emerging contaminants.

As well as potential capacity for 180 x 20 mL headspace vials, the system offers excellent reproducibility, and the sample preparation robot demonstrates high accuracy and precision for collection of the aqueous sample from the flow cell.
