AUXILIARY FLOW ELECTRODE (VERSIONS) Russian patent published in 2015 - IPC G01T1/169 

FIELD: instrumentation.

SUBSTANCE: auxiliary flow electrode comprises chamber 7 filled with electrolyte wherein overpressure is created by spring-loaded sleeve 9. Electrode electrolytic gate is composed of capillary 10 fitted in sleeve 9 where through electrolyte flows from chamber 7 to analysed medium. Electrode body 1 comprises electrolytic contact cell 5 communicated via channel 8 with chamber electrolyte. Chamber 7 is composed by cylinder-piston link. Note here that electrolyte filled in said chamber is sealed and electrically isolated. In compliance with first version (fig.1) said cylinder is arranged in the case 1.Piston-like sleeve 9 is fitted in said cylinder by means of, for example, oil gate 16. In compliance with second version (fig. 2), it differs from said first one in that said cylinder is arranged in sleeve 9. Piston-like case 1 is fitted in said cylinder.

EFFECT: stable electrode potential and higher reliability.
