ULTRON ES-CD

ULTRON ES-CD and ULTRON ES-PhCD are enantiomeric separation columns chemically bonded with

β-cyclodextrin (CD) and phenylcarbamated β-cyclodextrin (PhCD), respectively.

■ Features

1. Capable of chiral separations of hydrophobic cyclic compounds.
2. Both reverse and normal phase eluents can be used.
3. Chiral separations of a wide range of compounds are possible using these two types of columns.
4. Display superior stability and durability.

■ Characteristics

① ULTRON ES-CD and ULTRON ES-PhCD are effective for the enantiomeric separation of hydrophobic

cyclic compounds.

② Mobile phase of both reverse-phase and normal-phase modes can be used for the separation.

③ A wide range of enantiomeric compounds can be separated with ULTRON ES-CD or ULTRON ES-PhCD.

④ The columns show excellent stability and durability.

■ Applications

・Pharmaceutical compounds, Pesticides and Organic compounds
