Description

Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.

The chiral stationary phase in β-DEX 325 columns contains 2,3-di-O-methyl-6-0-TBDMS-β-cyclodextrin embedded in an intermediate polarity phase. The Supelco β-DEX 325 is similar in both chemistry and use to the CHIRALDEX B-DM phase, the main difference being the concentration of the dimethyl-derivatized cyclodextrin that is doped into the polysiloxane carrier.
