the vial. This ensures that the same conditions are kept constant across all vials. For example, in this study the following volumes have been used: • Vial 1 (sample + 7 μL water) • Vial 2 (sample + 1 μL standard + 6 μL water) • Vial 3 (sample + 3 μL standard + 4 μL water) • Vial 4 (sample + 5 μL standard + 2 μL water)
Available Certified to meet EPA Performance Based Specifications for Volatile Organic Analysis, Processed the same way as the certified vials but without certification documentation, or Unprocessed and ready for your own cleaning procedure. Amber vial for water sample collection for volatile organic analysis (VOA)
with volatile organic solvents. The cold trap auto-drains is under the control of the evaporator to ensure that high solvent recovery is maintained, no matter what mix of solvents are being used. Concentrates or dries up to 18 ASE vials
Using static headspace, sealed vials containing sample are gently heated to drive VOC compounds out of the sample matrix into equilibrium with the gas phase. Once stabilized the gas phase within the vial is then collected or directly transferred to the instrument for analysis.
The high-quality glass and plastic bottles are chemically and biologically inert. This allows even volatile organic substances or non-hazardous chemicals to be contained for an extended time period. Plastic bottles are flexible and perform well for squeezing functions, at low temperatures, or when unbreakable instruments are preferable.

Use these general purpose vials with all common counters. Fisherbrand™ 20mL Borosilicate Glass Scintillation Vials with white polypropylene caps feature potassium-free glass composition which provides consistently low activity counts and excellent light transmission.
A Thermo Fisher DSQ II MS and Focus TM GC and HT3 TM Automated Headspace Analyzer were used for the analysis of several food contact packaging materials. Various contact packaging materials were investigated for this poster and the products as well as sample size are presented in Table 1. Samples were added directly to a 22mL headspace vial.
not appropriate for the analysis of the more volatile organochlorine pesticides (e.g., the BHCs), because of losses during the drying process. For sediment and soils (especially gummy clay) that are moist and cannot be air-dried because of loss of volatile analytes, mix 5–10 g of sample with an equal amount of Dionex ASE Prep DE
Thermo Scientific™ Clear VOA Vials with Closed Cap are designed for EPA volatile organic analysis (VOA). Closed-top vials for VOA sampling when a pierceable septa closure is not needed. Available Certified to meet EPA Performance Based Specifications for Volatile Organic Analysis, Processed the same way as the certified vials but without
Apply EPA Volatile Organic Analysis (VOA) methods when using Thermo Scientific™ Narrow-Mouth Septa Bottles. Available as clear or amber Type III soda-lime glass, these bottles feature a cap with molded-in septa retainer ring which holds the pierceable PTFE-faced silicone septa securely in place without bonding to the cap so septum can be removed and replaced as needed (except 1L bottle).
