the sample vials with the purge bottle. The extraction system allows the installation of differently sized purge bottles and quantitative transfer of sample water from standard VOA vials into the extraction line via a septum. The GC injector connects to the six-port (V2) valve and the cryotrap for sample transfer
Newly manufactured bottles and vials may contain release agents and contaminants from the manufacturing factory which coats all surfaces of these bottles or vials on both the inside and outside. Conditions of storage or transportation also have the possibility of adding contaminants as well.

• During sample collection, make sure that the tap or spigot does not contact the sample container. • Samples collected in zero-headspace vials (i.e. volatile organic analysis (VOA), or total trihalomethanes (TTHMs)) must not have any headspace (see Section 1.5). All other sample containers must be filled with an allowance for ullage.
Oct 09, 2014 · Bottles used to collect samples for bacteria should be sterilized. The size of the container is important to ensure you have enough sample to run the analysis needed. Container size may also be affected by regulation, as larger samples may be needed to obtain lower detection levels.
B. Regulatory Voa Vial-- The actual voa sampling vial to b e submitted to the laboratory for analysis. The regulatory voa vial shall contain the same amount of chlorine reducing agent and acid as was determined with the experimental voa vial. C.
