Descripción

General 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 Supelco γ-DEX 325 columns contains 2,3-di-O-methyl-6-0-TBDMS-γ-cyclodextrin embedded in an intermediate polarity phase.
