Abstract
An electrochemical analysis system includes a chamber ( ) that defines a fluid receiving reservoir therein. A working electrode ( ), a reference electrode ( ), and a counter electrode ( ) is mounted to the chamber. An electrochemical analysis circuit ( ) applies appropriate voltages to the electrodes and reads appropriate currents from the electrodes to provide an indication of the peroxyacetic acid concentration in a sample. The working electrode includes a glassy carbon rod ( ) which is surrounded by a compressible polymeric sleeve ( ) and a metal sleeve ( ). One end of the metal sleeve is swaged ( ) to form a fluid tight compression seal with the insulating sleeve and the glassy carbon rod. An electrically conductive thermal extension joint between the glassy carbon rod and an electrically conductive rod ( ) includes a bore ( ) in the conductive rod in which the glassy carbon rod is slidably received and a compressed spring ( ) in the bore.
