DEVELOPMENT OF RENEWED MERCURY MULTIPURPOSE (MULTIMODE, VERSATILE) MICROELECTRODES, A PART OF PC-CONTROLLED MEASURING SYSTEMS (INCLUDING THE PC-ETP)

Information is given about the development of renewed miniaturized mer cury multi-purpose (multimode) electrodes as an inseparable part of th e development of modem 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, s mu E a nd mu E) Their spontaneously growing, step-wisely growing, stationary and contracting (compression) modes are schematically outlined. Inform ation 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 volt ammetry is given.
