| Minimum Volume/Size Required | 40 mL Glass vials with silicon/Teflon (PTFE) liners required. Collect three (3) vials of sample. Collect two (2) vials for a field blank |
| Storage/Preservation Prior to Shipping | • Add 3 mg sodium thiosulfate to each 40 mL vial (to dechlorinate). • Open the tap and allow the system to flush until the water temperature stabilizes, at least 5 minutes. Turn flow down to a smooth, pencil thin stream. • Remove cap from the bottle, tilt, and place under stream. • Sampling equipment must be free of plastic tubing, gaskets or other parts that may leach interfering analytes into the sample • Fill the container with sample water. Mix for one minute until the sodium thiosulfate is completely dissolved. • Store at 4°C. • Store samples away organic solvent vapors. |
