Request Information |
Merck offers a broad range of HPLC columns that are fully compliant with USP (United States Pharmacopoeia) specifications. L10 USP columns are described as cyano groups (CN) chemically bonded to porous silica particles, 3 to 10 µm in diameter. Our portfolio includes highly reliable L10 USP columns, such as LiChrospher® CN (10 µm).
Excellent Separations of Complex Samples
Having both polar and hydrophobic properties, LiChrospher® 100 CN (10 µm) can combine polar and weakly hydrophobic interactions – making it the ideal HPLC column for complex samples. This highly versatile sorbent is suitable for normal-phase and reversed-phase applications, as well as for selective charged interactions.
Features and Benefits
- Classified as L10 USP column
- Combines polar and weak hydrophobic interactions
- Successful HPLC of complex samples
