The sample accuracy and precision surpasses that of no-purge sampling devices that can cause low VOC recovery and suffer from elevated sample turbidity that can bias sample results. There are two models of Snap Sampler modules – one holds the 40 mL VOA bottles and the other holds either a 125 mL or 350 mL plastic bottle. Up to six modules can be connected in any combination and deployed at 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).

The Snap Sampler dedicated passive sampling system is the easiest way to collect samples for VOCs, SVOCs, metals and more. The Snap Sampler system has several advantages over other passive and no-purge sampling devices. Unlike passive diffusion bags that are limited to sampling for a small set of volatile organic compounds (VOCs), the Snap Sampler system collects a whole water sample that can be analyzed for any parameter – VOCs, SVOCs, metals other inorganic parameters, pesticides and nutrients.
