- EC HPLC column (analytical), NUCLEODEX BETA-PM, 5 µm, 200x4 mm
Cyclodextrin-modified silica phases for HPLC enantiomer separation. For all permethylated phases the ability to form hydrogen bonds is reduced, the hydrophobicity of the phase is increased compared to β‑OH, resulting in shorter retention times.
