Solid working electrode with replaceable tip

摘要

A working electrode for cyclic voltammetry experiments and the like provides an electrode carrier releasably attaching to replaceable tips each holding a solid working electrode material that may be polished for receipt of a reactant material and which electrically connects to an electrode in the electrode carrier when the tip and carrier are connected.

1. A solid, working electrode for electrochemistry tests comprising:
an electrode carrier having: (a) an elongate insulating shaft having opposed first and second ends separated along a shaft axis; (b) a carrier conductor passing between the first and second ends along the shaft axis through the insulating shaft to be surrounded in a direction radial to the axis by the insulating shaft, the electrode conductor exposed at the first and second ends for electrical connection thereto; and an electrode tip releasably attachable to the electrode carrier, the electrode tip having: (a) a solid surface working electrode conductor electrically connecting to the carrier conductor at the second end of the insulating shaft when the electrode tip is attached to the electrode carrier; (b) an insulating material attached around at least a portion of the working electrode conductor to seal a connection between the working electrode conductor and the carrier conductor against liquid infusion when the electrode tip is attached to the electrode carrier; and (c) attachment elements on the electrode tip and electrode carrier releasably retaining the electrode carrier and electrode tip in attachment; wherein the attachment elements are first and second magnets positioned on the electrode carrier and electrode tip respectively.
