Guidance for Sampling Soil and Waste Samples for Volatile Organic Compounds (VOCs)”. Related Guidance Method 5035A, “Closed-System Purge-and-Trap and Extraction for Volatile Organics in Soil and Waste Samples,” in Test Methods for Evaluating Solid Waste: Physical/Chemical Methods, SW-846, Third Edition, Final Update III; updated method:
Preservation Protocol. At first glance, the preservation protocol appears simple enough: Upon collecting an aliquot of the soil sample (typically 5 to 10 grams), immediately immerse it in vials containing methanol (typically 5 to 10 mL). Seal the vials and transfer them to the laboratory for subsequent analysis.
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.
