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 > Ion-sensitive or chemical field-effect transistors, i.e. ISFETS or CHEMFETS

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 > Ion-sensitive or chemical field-effect transistors, i.e. ISFETS or CHEMFETS

Of 4 combined children, 0 exist in both systems.

4 codes are CPC-only extensions.
