Development of renewed mercury multi-purpose (multi-mode, versatile) microelectrodes, a part of PC-controlled measuring systems (including the PC-ETP)

Information is given about the development of renewed miniaturized mercury multi-purpose (multi-mode) electrodes as an inseparable part of the development of modern polarography and voltammetry; casette-type, pen-type and PC-controlled systems, incl. the polarographic/voltammetric set. According to the experimental behavior and ranges of their radii the regimes of renewed stationary mercury electrodes are divided into three categories – mini-, semimicro- and microelectrodes (mE, sμE and μE). Their spontaneously growing, stepwisely growing, stationary and contracting (compression) modes are schematically outlined. Information on basic functional properties of the discussed renewed mercury semimicro- or microelectrodes using meniscus and microdrop-electrodes, by means of the d. c., anodic stripping and adsorptive stripping voltammetry is given.
