Those compounds must be analyzed from an unpreserved VOA vial. 5035 VOC HT - **Analysis must be completed 48 HOURS if samples are not frozen.** If Sample vials are frozen to < -7 C but above -20 C (or methanol), then HT is 14 days from collection.
After mixing, multiple aliquots of the composited sample are poured into VOA vials and sealed for subsequent analysis, or an aliquot can be poured into a syringe for immediate analysis. Purge Device Compositing (40 CFR 141.24rfiri4irv1) Equal volumes of individual grab samples are added to a purge device to a total volume of 5 or 25 mL The sample is then analyzed.
