Abstract
A method for the calibration of a device for measuring the total organic carbon content (TOC) of an aqueous solution by measuring resistivity. The method includes the following steps, in the presence of a reference TOC analyzer: (a) producing a calibration point by a measurement carried out on ultrapure water by the device and the analyzer; (b) producing a plurality of calibration points, each calibration point corresponding to a measurement of the resistivity of a solution having a given content of photo-oxidizable compound, by the device and the analyzer, in order to establish a correlation between the values measured by the device and the analyzer; and (c) calibrating the device by at least one algorithm, based on the measurements carried out in the previous step.
