Measuring deposition or liberation of materials from an electrolyte; Coulometry, i.e. measuring coulomb-equivalent of material in an electrolyte

Introduced: September 1968

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 > Measuring deposition or liberation of materials from an electrolyte; Coulometry, i.e. measuring coulomb-equivalent of material in an electrolyte

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) > Measuring deposition or liberation of materials from an electrolyte; Coulometry, i.e. measuring coulomb-equivalent of material in an electrolyte

CPC subdivides this area 3x more granularly than IPC with 2 additional codes.

2 codes are CPC-only extensions.
