McClellan - Case Study

Snap Sampler returns the best comparisons... with the Snap Sampler. The "McClellan Study" is a multi-agency test study conducted at the former Mc- Clellan Air Force Base in Sacramento, California. In the final report, Parsons describes the Snap Sampler as "...more consistently representative..." Correlation Coefficients (R2) for the Snap Sampler were the highest of all the methods tested ...

VOC Removal Device

The technique used to fill a VOA vial is at least as important a source of variance in VOC analysis as is well purging protocol or sampler design. The more the sample stream is agitated or exposed to the air during the transfer of sample from the bailer to the vial, the lower the concentration detected in the vial will be. The greatest loss of VOC's occurs when the sample is simply poured into ...
