SOLINST 425 DISCRETE INTERVAL SAMPLER

SOLINST 425 DISCRETE INTERVAL SAMPLER Great for sampling directly from a specific depth! Discrete interval sampling can be used to collect samples from distinct levels or points of inflow, to obtain representative water samples from below floating product layers ( LNAPL) , and to obtain samples of sinking product layers ( DNAPL) . Pumping and purging, and mixing of water from different levels in the well is minimized. Method of Operation Before lowering the sampler into the well, pressurize it using the high pressure hand pump ( included) . This prevents water flowing through the sampler on the way down the well. Once the desired depth is reached, the pressure is released and hydrostatic pressure allows the sampler and tubing to fill with water directly from the sampling zone. The stainless steel sampler is easily disassembled for decontamination. Applications Obtaining a representative groundwater sample from below oil/ product layers Discrete interval sampling Chemical profiling of wells Sampling at points of inflow to well LNAPL & DNAPL sampling System Includes: Reel, Tubing, Hand Pump, Sample Release Device ( SRD)
