METHOD AND DEVICE FOR MEASURING THE PURITY OF ULTRAPURE WATER |
摘要 |
<p>This is a method for analyzing the purity of water at the outlet from a purification device. It includes the following steps: a) sending the liquid at the outlet from the filter means to a resistivity measuring cell to determine its resistivity rhoUPW; b) establishing a reference mode by exposing a portion of the liquid to said oxidation means (2) during a given number of significantly different time periods; c) determining by regression the resistivity at infinity rho∞REF of said liquid in this reference mode; d) establishing an analysis mode by causing said liquid to be analyzed to pass through the resistivity measuring cell; e) determining the resistivity at infinity rho∞of said liquid in this analysis mode by successive iterations; and f) calculating the quantity of organic compounds contained in the purified liquid from this resistivity at infinity rho∞and at least the values rhoUPW and rho∞REF.</p> |
