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:

IPC:

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

CPC:

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

No child classifications to compare. This is a leaf node in both IPC and CPC.
