Abstract
A demountable, rectangular, liquid sample flow cell is provided which can be used to make streaming potential or streaming current measurements from which the zeta potential is calculated. By providing an infrared transparent window in the flow cell, a real-time monitoring of surface deposition rates and amounts can be determined by infrared radiometry. Because the flow cell is completely demountable, direct analysis of the internal surfaces exposed to the flowing solution is possible.
