Excellent chiral columns from the Lion City

ChiralCE and ChiralCD CSPs separate 80% of chiral compounds

ChiralTek Pte Ltd. of Singapore provides two series of chiral columns for traditional HPLC and modern UHPLC: a novel type of ChiralCE series of chemically-derivated cellulose-bonded chiral columns and ChiralCD series of chemically-substituted cyclodextrin-bonded silica particles-packed chiral columns.
The new ChiralCECD columns contain a unique complex chiral selector (cellulose-appended cyclodextrin) with two recognition moieties: cellulose and cyclodextrin. Due to the cooperative functioning of the cellulose and cyclodextrin, the ChiralCECD columns can provide different and generally better chiral separation for a wide range of chiral compounds.

Column protection

The ChiralCE and ChiralCD columns are shipped in a mixture of methanol/isopropanol. For use under reversed-phase conditions, the columns should be flushed with methanol following by mobile phase until reaching a constant column pressure. Similarly, for use under normal-phase conditions, the columns need to be flushed with isopropanol following by mobile phase until achieving a stable baseline signal.
A standard C18 guard cartridge can be used for reversed-phase conditions and a DIOL guard cartridge for normal-phase conditions to protect the analytical columns.
