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

SAMPLING METHOD FOR VOLATILE ORGANIC COMPOUNDS (SMVOC)

2.1 This method employs a sampling module and meter box to withdraw a 20-L sample of effluent gas containing volatile organic compounds from a station ary source at a flow rate of 1 L/min, using a glass-lined probe heated to 130 ± 5EC and a sampling method for volatile organic compounds (SMVOC) train.

XAD-2 resin has a higher collection efficiency for volatile PAHs than PUF, as well as a higher retention efficiency. However, PUF cartridges are easier to handle in the field and maintain better flow characteristics during sampling. Likewise, PUF has demonstrated its capability in sampling organochlorine pesticides and polychlorinated biphenyls.
