Optical investigation techniques, e.g. flow cytometry

Introduced: January 1985

Full Title

Investigating characteristics of particles; Investigating permeability, pore-volume or surface-area of porous materials > Investigating individual particles > Optical investigation techniques, e.g. flow cytometry

CPC subdivides this area 4x more granularly than IPC with 11 additional codes.

11 codes are CPC-only extensions.

Note: 7 CPC extensions are marked as secondary classification only.

IPC defines codes here since 2024.
