The industry accepted standard to measure residual water and oil saturation is by the Dena Stark Method.
Laboratory grade toluene is predistilled to ensure that water, if any in the toluene is removed prior to the analysis
The samples are placed in preweighed glass tares (not fiberglass tares) and loaded in the Dean and Stark Apparatus.
The samples are run for continuous minimum period of 72 hours during which water collected in the receiving tubes are monitored.

The receiving tubes come with Drain Valves at the bottom and the receiving tubes have to be calibrated.

You can also have the option of various capacity receiving tubes with no drain valves, ideal for tracer analyses.
