Abstract
A system and method for voltammetric analysis of a liquid sample solution.
Claims38
An electroanalytic device, comprising:
- (a) an electroanalytical cell comprising a working electrode, an auxiliary electrode, and a reference electrode;
- (b) a degassing system in fluid communication with the electroanalytical cell;
- and
- (c) a circulating means for continuously circulating a sample through the electroanalytical cell and the degassing system.

A system for voltammetric analysis, comprising:
- (a) a separation chamber for receiving a liquid sample solution;
- (b) an electroanalytical cell comprising a working electrode, an auxiliary electrode, a reference electrode, and a mercury chamber;
- (c) a flow channel for providing fluid communication between the separation chamber and the electroanalytical cell;
- (d) a degassing system for degassing the liquid sample solution, the degassing system in fluid communication with the electroanalytical cell and the separation chamber;
- and
- (e) a pump for circulating the liquid sample solution through the separation chamber, the electroanalytical cell, and the degassing system.

A method for voltammetry, comprising the steps of:
- (a) introducing a liquid sample solution into an electroanalytical cell of an electroanalytic device, wherein the electroanalytical device further comprises a degassing system and a pump;
- (b) pumping the liquid sample solution through the electroanalytical cell to the degassing system;
- (c) introducing an inert gas into the degassing system, thereby causing separation of dissolved gas from the liquid sample solution and providing a degassed liquid sample solution;
- (d) pumping the degassed liquid sample solution into the electroanalytical cell;
- and
- (e) making a voltammetric measurement of the degassed liquid sample solution.
