High quality groundwater sampling explained

The Solinst Technical Bulletin on High Quality Groundwater Sampling explains how to obtain representative groundwater samples using Solinst Bladder Pumps, 464 Electronic Pump Control Units and our 12 Volt Compressor. Solinst Bladder Pumps are designed for sampling in a variety of applications and are ideal for obtaining VOC samples. This bulletin describes where it is best to use stainless steel Bladder Pumps or PVC Bladder Pumps, and tips for setting the Control Unit to achieve your desired sampling rate. The 464 Control Unit works with Bladder Pumps, automatically or manually with a 12 Volt Compressor, to provide low or high flow sampling to depths of 500 ft (150 m).
