摘要： A method for monitoring the effectiveness of an ion exchange module in an ultrapure water purification circuit containing ultrapurified water and having a purified water inlet and a point of use outlet and a memory, the method comprising the steps of: (a) passing the water in the circuit through the ion exchange module a multiple of times to provide ultrapurified water; (b) measuring the resistivity of the ultrapurified water provided by step (a) using one or more sensors to provide an ultrapurified benchmark resistivity value R-i; (c) storing the value Ri in the memory; (d) introducing purified water into the circuit through the inlet; (e) passing the water in the circuit including the purified water of step (d) through the ion exchange module; (f) measuring the resistivity of the water after step (e) to provide a new water resistivity value RneW; and (g) comparing Ri and Rnew to determine the effectiveness of the ion exchange module. In this way, comparing the impact on the resistivity of newly introduced purified water after its first passage through the ion exchange module with the benchmark resistivity value Ri provides a better indicator of the effectiveness of the ion exchange module.
