MULTIPLE MICROELECTRODE AND PROCESS OF ITS MANUFACTURE

摘要

FIELD: measurement technology, measurement of concentrations of solutions. SUBSTANCE: multiple electrode has dielectric carrying rod which carries microelectrodes of microwire and current conduits 4. Rod is coated with dielectric layer that is partially ground off and open sections of microwire present working sections 5 of microelectrodes. Section of rod has shape of n-angle piece or n-pronged star ( n>2 ). Current conduits are arranged uniaxially to rod. Microelectrodes are made from microwire having diameter d that is put on rod in the form of spiral with spacing t<EMI ID=0.191 HE=3 WI=3 TI=CHI>10 d. Dielectric coat in process of manufacture of multiple microelectrode is ground off on ribs of rod to form breaks of microwire which value is S<EMI ID=0.192 HE=3 WI=3 TI=CHI>10d . Rod can be made from metal or dielectric with metal coat. In the latter case current conduits are not installed. EFFECT: decreased labor input and improved operational reliability. 4 cl, 9 dwgs
