Request Information |
MilliporeSigma offers a broad range of HPLC columns that are fully compliant with USP (United States Pharmacopoeia) specifications. L20 USP columns are described as dihydroxypropane groups chemically bonded to porous silica particles, 3 to 10 µm in diameter. One of our high-quality HPLC columns that meets L20 USP requirements is: LiChrospher® DIOL (5 µm).
Ideal for Complex Samples and Exclusion Chromatography
LiChrospher® DIOL (5 µm) exhibits both polar and hydrophobic properties, and combines weak hydrophobic interactions with polar interactions. This enables successful HPLC separations of complex samples. Furthermore, LiChrospher® DIOL is also suitable for exclusion chromatography.
Features and Benefits
- Classified as L20 USP column
- Combines weak hydrophobic interactions with polar interactions
- Successful HPLC of complex samples
- Suitable for exclusion chromatography
