(PDF) Determination of Volatile Organic Compounds (VOCs

Inside an organic chemical laboratory, it was found to be 0.30 ppb (Lee et al., 2002). 1 μg/m 3 of benzene was observed in classrooms at the Aquitaine region near Bordeaux, France (Larroque et al

Method 624: Purgeables - United States Environmental

Samples can be contaminated by diffusion of volatile organics (particularly fluorocarbons and methylene chloride) through the septum seal into the sample during shipment and storage. A field reagent blank prepared from reagent water and carried through the sampling and handling protocol can serve as a check on such contamination. 3.3

Taking a VOC (Volatile Organic Chemical) Sample Properly

Taking a VOC (Volatile Organic Chemical) Sample Properly Make sure you keep all the vials together the whole time you are taking your The samples must be sent to the lab immediately. The sample will NOT be usable if there is an air bubble in the sample. You will have to resample. Step One Get a Sample Kit From Your Lab – One vial will be

2.2 The sample plug is immediately extruded into a glass vial containing organic-free reagent water. The vial is immediately covered with aluminum foil and a modified septum cap. 2.3 The sealed vial containing the sample is hand-shaken for 10 - 15 sec and the sample is visually examined to ensure that complete dispersion of the sample in the

Continue filling the sample vial until it almost overflows. Immediately cap the vial with the smooth (Teflon) side of the septum in the cap toward the sample. No air bubbles should pass through the bottle as it is being filled or be trapped in the sample as the bottle is sealed. Repeat steps 4 through 6 for the second vial.

The vial was then closed with a cap containing polytetrafluoroethylene (PTFE)-coated rubber septum and kept at 50 °C for 60 min. Headspace gas-chromatographic analysis was performed by manually injecting 1.0 mL of the vial headspace from each sample by means of a 1.5-mL Hamilton gas-tight syringe (temperature kept at 50 °C).

Volatile Organic Chemicals. Samples collected for Volatile Organic Chemical (VOC) analysis need to be collected in pre-cleaned, pre-preserved 40 mL vials that are available at the laboratory. These vials contain hydrochloric acid (HCl) and therefore should be handled with caution. Take care not to touch or otherwise contaminate the inside of
