Control of physical parameters of the fluid carrier

Introduced: January 1985

Full Title

Full titles differ between systems:

IPC:

Investigating or analysing materials by separation into components using adsorption, absorption or similar phenomena or using ion-exchange, e.g. chromatography > Column chromatography > Conditioning of the fluid carrier; Flow patterns > Control of physical parameters of the fluid carrier

CPC:

Investigating or analysing materials by separation into components using adsorption, absorption or similar phenomena or using ion-exchange, e.g. chromatography (G01N3/00, G01N5/00, G01N7/00, G01N9/00, G01N11/00, G01N13/00, G01N15/00, G01N17/00, G01N19/00, G01N21/00, G01N22/00, G01N23/00, G01N24/00, G01N25/00, G01N27/00, G01N29/00 take precedence) > Column chromatography > Conditioning of the fluid carrier; Flow patterns > Control of physical parameters of the fluid carrier

Of 5 combined children, 4 exist in both systems.

1 codes are CPC-only extensions.

Note: 1 CPC extensions are marked as secondary classification only.

2 shared codes have differing titles between IPC and CPC.
