摘要

硅胶整体棒是整体分离柱中用作填料的无机材料，整体分离柱是材料分离特别是高效液相色谱（HPLC）的全球发展趋势。与以前广泛使用的球形硅填料分离柱不同，这些整体柱在制备棒过程中存在各种问题，包括收缩、变形和开裂，限制了它们的应用。本文介绍了一种新型硅胶整体棒的研制，该棒在高效液相色谱中可显著缩短分析时间，同时保持较高的分离效率。

Establishment of Preparation Conditions for Silica Monolithic Rods Using the Sol-Gel Method and a Study on Their Characteristics

Silica monolithic rods are inorganic materials used as packing materials in monolithic separation columns, a global trend in material separation, particularly in high-performance liquid chromatography (HPLC). Unlike the previously widely used separation columns with spherical silica packing, these monolithic columns suffer from various problems, including shrinkage, deformation, and cracking during the preparation of rods, limiting their application. This paper describes the development of a new type of silica monolithic rod that can significantly shorten analysis time while maintaining high separation efficiency in HPLC.
