MEB
SMT METHYL (C1)
Unique features:
- SMT MEB phase with the least hydrophobicity; the functional ligand density provides only about 1% carbon load on the silica substrate.
- Offers selectivity for polar and nonpolar pharmaceuticals, natural products, very hydrophobic proteins and biomolecules.
- Longer column lifetime than traditional C1 columns.
SMT ETHYL (C2)
Unique features:
- SMT MEB phase with two carbon chains. The functional ligand density provides about 1.2% carbon load on the silica substrate.
- MEB2 is also suitable for analysis of very hydrophobic proteins and biomolecules. More suitable for separation in mildly aggressive pH conditions than MEB1.
- Longer column lifetime than traditional C2 columns.
SMT BUTYL (C4)
Unique features:
- SMT MEB phase with four carbon chains. The functional ligand density provides about 3% carbon load on the silica substrate.
- Most hydrophobic of all MEB columns; designed to tolerate mildly aggressive pH conditions that may hamper usage life of MEB1 and MEB2 columns.
- Excellent peak symmetry; offers very good selectivity for polar and moderately nonpolar pharmaceuticals and biomolecules.
- Longer column lifetime than traditional C4 columns.
