into methanol and samples where methanol was added at a later time to soil extruded into empty VOA vials (where methanol was added through the septum). Based on these findings, where project or program DQOs require a higher degree of accuracy soil samples may need to be chemically preserved in the field.

Figure 1 and 11 VOA vials were filled by transfer-ring the spiked water solution under nitrogen pressure. VOA spiked samples were prepared by adding 100 µL of the 50.0-µg/mL three component solution and 100 µL of the 100-µg/mL 60-component VOC standard to 500 mL of water in a 1.0-L screw cap bottle. After inverting to mix thoroughly, this bottle
for sample preparation and analysis in the laboratory. Use of these containers for sampling helps minimize loss of VOCs resulting from opening sample containers and/or transferring materials from one container to another. Certified pre-cleaned VOA vials are commonly used as sample containers for VOCs and are
