General description
β-DEX 110 柱中的手性固定相包含嵌入中极性固定相的全甲基化 β-环糊精。建议将它们用于众多手性化合物(酮、酯、烷烃、烯烃、醇、酸、酯等)的对映异构体分离。10%(β-DEX 110) 和 20% (β-DEX 120) β-环糊精的含量保持相似的对映立体选择性,但改变了流出的顺序。
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.
