Study of Five Discrete Interval-Type Groundwater Sampling Devices
A study and comparison of five groundwater samplers used for discrete interval sampling is presented. Each device was analyzed to determine whether they are able to provide representative samples as claimed. Ease of use, and analytical results from each sampler are compared. The study includes the Solinst Discrete Interval Sampler, as well as other grab samplers and some diffusion-based devices.

An Analysis of Low-Flow Ground Water Sampling Methodology
Discussion on ground water sampling from wells using low-flow sampling methodology. Arguments are presented to support slug or passive sampling from wells with relatively low hydraulic conductivity. Low-flow sampling is recommended to reduce accumulation of sediments in wells routinely sampled if drawdowns are minimal.

Performance testing of conventional and innovative downhole samplers and pumps for VOCs in a laboratory monitoring well. Baerg et al., 1992
This paper presents the results of an evaluation of several sampling devices in a controlled laboratory setting. Their evaluation includes small-diameter sampling devices including inertial pumps , bailers, and peristaltic pumps. The authors evaluate the biases associated with volatilization and sorption of volatile organic compounds to sampling materials.
