Jan 01, 2001 · Samples for volatile organic chemicals were collected directly from stockpiles as well as from the fresh pile underneath the conveyer belt in 40-ml vials (I-Chem. Corp.) with Teflon lined septa. The volatile organic compound (VOC) vials were tapped slightly as they were filled to eliminate as much free air space as possible.

The vial was then closed with a cap containing polytetrafluoroethylene (PTFE)-coated rubber septum and kept at 50 °C for 60 min. Headspace gas-chromatographic analysis was performed by manually injecting 1.0 mL of the vial headspace from each sample by means of a 1.5-mL Hamilton gas-tight syringe (temperature kept at 50 °C).
