A system for the determination of trace-level polar and non-polar toxic organic compounds in ambient air
- Perkin Elmer Corp., Norwalk, CT (United States). Fresh Aire Lab.
A gas chromatographic system is described for the determination of toxic organic compounds in ambient air. These compounds include all those specified within the US EPA Compendium Method TO14 and some polar additional analytes under consideration for the proposed TO15 Method. The system supports both on-line and off-line (passivated canisters and adsorption tubes) methods for sampling air--providing a fully automated analysis. A key feature of the system is that liquid cryogen is not required for either the analyte preconcentration or the subsequent chromatographic separation. Water management is achieved by dry-purging an adsorbent trap upon which the sample analytes have been retained. The performance of the system is demonstrated with conventional detection systems (electron capture and flame ionization) and with a mass spectrometer.
