G01N 27/49 Systems involving the determination of the current at a single specific value, or small range of values, of applied voltage for producing selective measurement of one or more particular ionic species
Introduced: January 1990
Full Title
Full titles differ between systems:
Investigating or analysing materials by the use of electric, electrochemical, or magnetic means > by investigating electrochemical variables; by using electrolysis or electrophoresis > Systems > Systems involving the determination of the current at a single specific value, or small range of values, of applied voltage for producing selective measurement of one or more particular ionic species
Investigating or analysing materials by the use of electric, electrochemical, or magnetic means (G01N3/00 – G01N25/00 take precedence; measurement or testing of electric or magnetic variables or of electric or magnetic properties of materials G01R) > by investigating electrochemical variables; by using electrolysis or electrophoresis > Systems (G01N27/27 takes precedence) > Systems involving the determination of the current at a single specific value, or small range of values, of applied voltage for producing selective measurement of one or more particular ionic species
