TEFLON TUBING MERCURY-ELECTRODE FOR ELECTROCHEMICAL ANALYSIS

A 15 cm length of 0.5 mm ID Teflon tubing has been used as an electrod e for electrochemical analysis. A micrometer driven syringe has been u sed to produce mercury drops of different sizes. The stability and rep roducibility of the electrode in aqueous and non-aqueous media were in vestigated. The stability of the drop was shown to be superior to conv entional hanging mercury drop electrodes and reproducibility was shown to be about 1% which is comparable to other types of electrodes.
