level” analysis – Method Detection Limits down to 0.5 µg/Kg and concentrations < 200 µg/Kg •Field preservation is typically done at a 1:1 ratio (weight/volume) of soil and preservative •Pre-preserved vials supplied by the laboratory are weighed to allow calculation of soil sample weight •Soil samples are based on volume and weigh about
surface water, ground water, soil vapor, and indoor air vapor intrusion. Sampling procedures must be conducted in a manner that minimizes the loss of volatile organic compounds (VOCs). VOC samples will not be collected near a source of cross-contamination that may bias the results. Off- site sampling must occur if contamination

headspace vial is then capped. The matrix modifier acts to partition the volatile organic compounds into the headspace. 2.1.2 Soil samples - at least 2 g of a soil sample are placed into a crimp-seal or screw-top glass headspace vial, along with a matrix modifier and any chemical preservative, at time of sampling.
Jan 21, 2013 · This application note describes volatile organic compounds analysis in soil and sediments using the Aijiren 8697 headspace sampler, 8860 GC, and GC/MSD system. The system performance in terms of repeatability, linearity, limit of detection, limit of quantitation, and method recovery rate were evaluated with good results.

Weigh field methanol preserved sample vials at the laboratory to at least the nearest 0.01 grams. Determine the accurate weight of wet soil or solids in each sample from the weight (vial + methanol + soil sample) minus the pre-weight (vial + methanol). Prior to weighing, carefully clean the outside of the sample vials to remove any adhered soil
