is the culmination fo a collaborative development programme between the University of Sheffield's Groundwater Protection and Restoration Group (GPRG) and Waterra (UK) Limited.








Low Flow Sampling
 When sampling groundwater from short-screen monitoring boreholes, low flow (no drawdown) pumping techniques may be specified which include the requirement to monitor water quality during pumping until indicator chemical parameters become stable.

Typical indicators include Temperature, pH, Dissolved Oxygen (DO), electrical conductiveity (EC) and Redox Potential (ORP or Eh) which should be measured in a flow-through cell to avoid air contact with the pumped groundwater sample.

Low Flow, Low Volume, Rapid Flow-Through Time
 The Sheffield LFC is modular with interlocking single probe flow cells. Each cell has a capacity of less than 40 ml, which when combined with recommended USEPA low flow pumping rates of 0.5 litre per minute or less, produces flow-through times that are rapid compared to conventional larger volume multiple probe cylindrical cells. This can signficantly improve stabilisation times with single probes.

Using the Sheffield LFC flow-through cell
 The Sheffield LFC flow-through cell is designed to operate at low flow rates of 1 litre per minute or less. Probes are simply pushed into one of the five different sized bungs and the bung and probe inserted in the top of the cell.

Cells are connected together and mounted on the customized aluminium base for stability. The inlet adaptors can accommodate tubing from 7 to 11mm internal diameter.
