The Snap Sampler® dedicated passive sampling system is the easiest way to collect samples for VOCs, SVOCs, PFAS metals and more. There are two models of Snap Sampler modules – one holds the 40 mL VOA bottles and the other holds either a 125, 250 or 350 mL plastic bottle. Up to six modules can be connected in any combination to fit the testing requirements for that well. There are two triggering systems--a manual trigger and a pneumatic trigger--that deploy the Snap Sampler modules to the desired sampling depth within the well screen interval. There’s no depth limitation with the Snap Sampler system - samples have been collected at depths greater than 2,000 feet (600 m). Deep sampling, low yield wells and short water column wells are especially good candidates for the Snap Sampler, but any well greater than 2" in diameter is a potential candidate.
