RPC - Rotation Planar Chromatography

Rotation planar chromatography (RPC), as with OPLC, is another thin-layer technique with forced... [Pg.455]

Rotation planar chromatography (RPC) uses a centrifugal force for mobile phase migration, in addition to the capillary action. The size of the vapor space above the chromatographic plate is an essential criterion in RPC methods and, based on this, the methods are classified into four basic techniques, namely normal chamber RPC (N-RPC), microchamber RPC (M-RPC), ultra-microchamber RPC (U-RPC), and column RPC (C-RPC). [Pg.447]

Rotation planar chromatography (RPC), as with OPLC, is another thin-layer technique with forced eluent flow, employing a centrifugal force of a revolving rotor to move the mobile phase and separate chemical compounds. The RPC equipment can vary in chamber size, operative mode (analytical or preparative), separation type (circular, anticircular, or linear), and detection mode (off-line or online). The described technique was applied in analytical and micropreparative separation of coumarin compounds from plant extracts. [Pg.513]

In 2004, rotation planar chromatography (RPC), another forced-flow technique, was online coupled with... [Pg.1184]

Chamber types for rotation planar chromatography (RPC) differ according to the vapor space in N-RPC, the layer rotates in an unsaturated N-chamber in M-and U-RPC (Nyiredy et al., 1988b), the chamber is the saturated (M) and unsaturated (U) sandwich type (Nyiredy, 1992). In the M (micro)-chamber, the plate... [Pg.135]

Forced-flow planar chromatography (FFPC) with the use of external pressure (overpressured layer chromatography, OPLC) or centrifugal force (rotation planar chromatography, RPC) can be used for off-line or on-line PLC (Mincsovics et al., 1988 Nyiredy, 1990). In off-line FFPC, the procedures after development... [Pg.240]
