organic analysis (VOA) vials without preservatives as described in Method 5035A, Appendix A, sections A.7.0 and A.8.2.2. NOTE: Samples collected in VOA vials can only be analyzed one time. Therefore, collect at least three separate vials at each sample location: o one vial for low-level concentration analysis,
Apr 19, 2000 · EPA has permitted the use of methanol preservation for low level analysis if the target analyte(s) can be quantitated below 200 µg/kg. As a result, laboratories must demonstrate their ability to detect below 200 µg/kg to the client and ADHS. Samples preserved in the field with methanol using a 40 mL glass VOA vial with a
Figure 2: This is a 20mL VOA vial containing our soil sample and the methanol used to extract it. First, 10mL of purge-and-trap grade methanol was added to a 20mL VOA vial (shown in Figure 2 ). Then, the vial was capped and we determined its mass with an analytical balance. Next, we added 5 grams of our certified reference
6.11 VOA Vials - 40 mL with teflon septa. 7.0 REAGENTS 7.1 The following standards of known purity as neat material or solutions of certified concentration: 7.1.1 Trifluorotoluene (TFT)- Surrogate 7.1.2 Commercially Prepared Standard Solutions—Commercially prepared solutions are purchased and stored at -10 to -20°C.
1.2 The low soil method utilizes a hermetically-sealed sample vial, the seal of which is never broken from the time of sampling to the time of analysis. Since the sample is never exposed to the atmosphere after sampling, the losses of VOCs during sample transport, handling, and analysis are minimized.
3) Collect 2 low-level vials (preserved) Or One high-level vial. Method 5035 Sample Preservation Method 5035 addresses the preservation of the low concentration soil samples with sodium bisulfate to ensure a sample pH of 2. If using option 1, two pre-weighed sample vials with the sodium bisulfate
A 5-gram (g) aliquot of soil/sediment is weighed into a 40-milliliter (mL) Teflon-lined septum vial, 5 mL of commercially available water suitable for VOC analysis is added, and the sealed vial is placed in the autosampler. An additional 5-mL portion of commercially available water containing surrogate/internal standards is added by the

VOA bottles are KaptClean® for Volatiles and are designed for EPA volatile organic analysis (VOA). This method is also known as Protocol B. Volatiles are chemicals that have high vapor pressures at room temperature (easily evaporate). They can include benzene, chloroform, toluene and carbon tetrachloride. Vials are pre-cleaned based on OSWER
