A unique CD-Screen type column has been developed for separation of ionic cyclodextrin derivatives. The commercial name of this column is CD-Screen-IEC.

The chromatogram below demonstrates excellent separation power of CD-Screen-IEC column. The sample is a sulfobutylether-beta-cyclodextrin with degree of substitution 6.5 (SBECD, DS=6.5). The impurities (hydroxybutanesulfonic acid, HBSA; beta-cyclodextrin, BCD and 4,4’-oxybutane-1,1’-disulfonic acid, DBSA) are definitely separated from the cyclodextrin components.
cd-screen-iec-1

The same HPLC method was suitable for determination of DS, component distribution and quantitative determination of impurities (BCD, HBSA and DBSA).
cd-screen-iec-2
Modifying the HPLC method, quantification of degradation products is can be solved.
