Fabrication and Characterisation of Leak-Tight Glassy Carbon Electrodes, Sealed in Glass Employing Silicon Coating, for Use in Electrochemical Detection

High-Performance Liquid Chromatography of Catecholamines and their Metabolites in Biological Material

“…New glassy carbon cells with improved electrode performance have recently been constructed (Hoogvliet et al, 1983) as well as cells housing two electrodes working either in a parallel or in a consecutive configuration, thus improving the selectivity of detection (Mayer & Shoup, 1983).

Multichannel amperometric detection system for liquid chromatography and flow injection analysis

“…For the multi-working-electrode version, a modification of a homemade detector cell (PB-2) ha9 been used. Design, construction, and characterization of the electrodes, as well as the hydrodynamics and mass-transfer characteristics of the detector, have been described previously for the one-working-electrode version (25,26). A minor modification in the design of the multielectrode version has been made: a stainless steel capillary (i.d.…”

“…The auxiliary electrode was a glassy carbon (GC) disk of 10-mm diameter, sealed in a glass holder. Silicon was coated on the side of the glassy carbon disk by chemical vapor deposition to ensure a leak-free seed between the electrode material and the glass holder (25). The holder for the working electrodes has been made of poly(trifluorochloroethylene) (Kel-F).…”

“…In the construction of the latter electrode arrays, special care must be taken to prevent leakage from electrolyte solution in gaps between electrodes and the holes in the Kel-F holder, in which the electrodes are pressed. Otherwise, background and noise level may be excessive (25).…”
