Patent number: 5198988Abstract: A method of determining optimum operating potential in an electrochemical detector and an electrochemical detector for performing the method, particularly for use in connection with a liquid chromatograph, are disclosed. A control and data processing unit causes a plurality of different potentials to be successively applied in an electrochemical cell and a subsequent electrochemical detection of the sample to be performed at each of the potentials. After each adjustment of a new potential, the current behavior at the working electrode in the electrochemical cell is monitored by an amperometer. When the current behavior has stabilized, a trigger signal is produced by the unit which effects an injection of the sample into the separation column of the chromatograph. From the current signals at the working electrode obtained for the different potentials, it can be determined which potential gives optimum detectability of the sample.Type: GrantFiled: August 16, 1990Date of Patent: March 30, 1993Assignee: Hewlett-Packard CompanyInventors: Thomas Dorr, Clemens Linowski
