aqueous working samples should not exceed 50 ng/L. 7. Sample Collection, Preservation and Storage 7.1. Collect samples in duplicate in 40 mL amber VOA vials as described in method 524.2. 7.2. If the samples contain residual chlorine, add 25 mg of ascorbic acid to each vial before sample collection. 7.3. Store samples at 4°C until analysis.
The sample is transported to a lab for hydrocarbon analysis. 3. RANGE AND SENSITIVITY 3.1 Range and sensitivity are determined by lab analysis methodology and instrumentation. 4. INTERFERENCES 4.1 The water collection system and sample vials/bottles should be kept clean to prevent contamination. Sample vials/bottles should only be opened
These accessories are designed for use with VOA vials, vial caps, bottles, and jars, as well as environmental sample bottles. Sample Preservation Containers Make proper field preservation at the point of sample collection easier and safer.
the sampler is manually retrieved to the surface and the sample vials removed. The sample is then preserved, if required, and the vials are capped with positive-displacement-type caps that ensure a bubble-free sample. Sampler decontamination is carried out by rinsing the sampler in the field using a 5
Cooling of Samples Samples must be chilled to <6oC immediately following collection and packed with a sufficient amount of ice to maintain that temperature until receipt at laboratory facility. EPA protocols do not allow the use of icepacks or ice substitutes (blue ice) because they are unable to maintain a cold enough temperature.
