Astec ChiralDEX含TA、DM、DP、DA、PN、BP、PH、PM等固定相。Astec CHIRLDEX G-TA，G-DP，B-DM及Supelco β-Dex 110或120組合能完成絕大多數手性物質的氣相色譜分離。

Supelco α-DEX 120 氣相色譜手性柱包含嵌入中極性固定相的全甲基化 α-環糊精，對小分子對映異構體的分離具有*的選擇性。還建議用于分離位置異構體（酚、二甲苯等）。

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。

Supelco α-DEX 120 氣相色譜手性柱應用：
α-DEX^™ 120 was used in a GC column, in an experiment conducted to study the addition of catalytic enantioselective diethylzinc to a-substituted aldehyde, in presence of enantiopure ligand。It was also used to pack chiral column durin GC analysis, in an experiment to investigate lipase-mediated desymmetrization of glycerol with aliphatic and aromatic anhydrides。
