Article number: 51838
ENVIRONMENT
- Column packings
- CORTECS C18
- BEH C18
ANSWER
BEH C18 columns are packed with a fully porous, bridged ethylene hybrid (BEH) particle, with a trifunctionally bonded C18 ligand.
This packing is endcapped and has a pore diameter (pore size) of 130 angstroms.
CORTECS C18 columns are packed with a silica-based, superficially porous, solid core particle, with a trifunctionally bonded C18 ligand.
This packing is endcapped and has a pore diameter (pore size) of 90 angstroms.
