use the vial cap to top off the vial and form a meniscus. STEP NINE Screw the cap onto the vial with the Teflon side of cap liner face down, in contact with the water. Roll or shake vial to fully mix ascorbic acid. Carefully uncap vial and add 4 drops of HCL to the vial. NOTE: HCLmay cause burns so use proper eye, hand, and clothing protection

As stated previously the most common technique used to detect, identify and quantitate VOC is gas chromatography with flame ionization (FID), electron capture (ECD) or mass spectrometry (GC-MS) detection. Selection of a detection method requires consideration of various analytical parameters and regulatory requirements.

As part of the protocol for sampling VOCs, one best practice includes the use of Travel or Trip Blanks to monitor the integrity of the samples. Is possible to contaminate volatile samples while in transit or storage. To address this, the laboratory, on request, will provide organic - free water, sealed in VOA vials to accompany the sample
