Patent ID: 6841053

Claim:
An ozone detection system based on voltammetry, for detecting the presence and/or concentration of ozone in a liquid sample, comprising at least one working electrode comprised of one or more of the metals selected from the group consisting of Rh, Pt, Au, Os, Ru, Ni, Ti, and Re; a counter electrode; a programmable pulse generator capable of applying a predetermined sequence of energizing pulses to said at least one working electrode; a recording device for recording the output from said at least one working electrode generated in response to the applied pulse sequence; a sampling device for sampling values of said output at predetermined intervals; a memory for storing the sampled values in a matrix; a processing unit (PC) for performing a multivariate analysis of said matrix, and predicting a concentration of ozone based on the results of said multivariate analysis; and a display device for displaying the result of said multivariate analysis.
