摘要

摘要研究了带有硅胶吸附剂的毛细管多孔层析柱的直径对装载特性的影响。制备了三种直径分别为 0.25、0.32 和 0.53 毫米的毛细管多孔层析柱，其中硅胶吸附剂的直径为 0.25、0.32 和 0.53 毫米。使用直径为 0.32 毫米的规则多孔吸附剂的色谱柱的装载能力是相同直径的商用 GS-GasPro 色谱柱的 7.3 倍。以分离 C4 脂肪烃为例，说明了进样量对色谱峰分辨率的影响。

Loading Properties of Capillary Porous-Layer Columns of Different Diameters with a Silica Gel Sorbent

Abstract

The effect of the diameter of a capillary porous-layer column with a silica gel sorbent on the loading properties was studied. Three columns with diameters of 0.25, 0.32, and 0.53 mm with a regularly porous silica gel sorbent were prepared. The loading capacity of the column with a regularly porous sorbent with a diameter of 0.32 mm was 7.3 times higher than for a commercial GS-GasPro column of the same diameter. The influence of the amount of the injected sample on the resolution of chromatographic peaks was shown using the separation of C₄ aliphatic hydrocarbons as an example.
