• Remove the VOA vial cap. • Slowly fill the vial with the water sample. • To achieve ZERO HEADSPACE, the water sample must for a “dome” on top just before overflowing. • Carefully add 2 - 4 drops of the HCl acid from the dropper provided to the vial filled with water. • Replace the vial cap securely.
Vials and containers with septa caps are most commonly cleaned for volatiles. Containers are cleaned based on OSWER directive from the EPA. Certifications are completed at an independent laboratory. Analytes that are commonly analyzed: Purgeable Volatile Organics; Halogenated Volatile Hydrocarbons; Aromatic Volatile Hydrocarbons

Two 40 ml VOA vials will be filled in a manner limiting agitation and aeration for each of the samples for routine volatile organic analyses. The bottles will be filled such that a meniscus is formed on the neck of the bottle. The bottle will be carefully capped and the vials will be inverted and tapped slightly to inspect for air bubbles. If

Add 25 mg of ascorbic acid to sample vials before filling. After the vial is filled to overflow, then add one to two drops of 1:1 HCl for each 20 ml of sample volume to a pH of <2. Seal the vial taking care not to trap any air bubbles. Turn vial septa-face down, and shake vigorously for 1 minute. Collect samples in duplicate 40ml VOA vials. EPA
The Sample Storage Vials produced by Aijiren have many different capacities. In order to adapt to different customers, they have 24mm openings and 24-400 standard threads. The sample storage vial can also be called EPA Vials.
Water sampling vials are ideal for water sample collection and storage when testing for pollutants. To meet EPA standards and prevent contamination, vials are prepared in a solvent-free facility. Test for toxicity with clear, white, or amber vials for ultraviolet sensitive samples. Since water sampling procedures demand immediate testing for

A second VOA vial (i.e., a Field Duplicate) is required as a means of ensuring that a back up sample is available, and for preparing FD, LFSM and LFSMD QC samples. 11.1.1 PREPARATION OF LFSM and LFSMD: SYRINGE METHOD - Three 40-mL vials (FDs) are required for a sample and its associated LFSM and LFSMD.
The containers used for collecting VOC samples are frequently volatile organics analysis (VOA) vials that are directly compatible with the equipment used for sample preparation and analysis in the laboratory. Use of these containers for sampling helps minimize loss of VOCs resulting from opening sample containers
glass amber sample bottles, 40-ml volatile organic sample vials and 1 liter poly containers. Three (3) 40-ml VOA vials, two (2) 1-liter amber bottles.(BNAs) and three (3) 1-liter poly samples (metals, dissolved metals, cyanides) will be collected at each location. In addition, two sample locations require double volumes for laboratory QC. All
