Cells and probes with solid electrolytes

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 > Cells and electrode assemblies > Cells and probes with solid electrolytes

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 > Cells and electrode assemblies > Cells and probes with solid electrolytes

CPC subdivides this area 3x more granularly than IPC with 3 additional codes.

3 codes are CPC-only extensions.

IPC defines codes here since 1990.
