This project, directed by Assistant Professor Luis A. Colon at SUNY-Buffalo, is supported by the Analytical and Surface Chemistry Program in the Division of Chemistry. The work will use sol-gel technology to synthesize chemically bonded stationary phases for use with chromatographic methods, particularly high performance liquid chromatography (HPLC) and electrochromatography in open and packed columns. The incorporation of the desired functional groups into the sol-gel reagents during the fabrication of the silica will create Si-C bonds that do not undergo hydrolysis and provide a material that is multilayered. These characteristics are especially promising for solving the existing problem of suitable packing and surfaces for separations at high pH. Studies will be done of the variables affecting the chemical reactions involved in the glass formation process. A number of techniques (ESCA, SIMS, FTIR and others) will be used to examine the physicochemical properties of the glasses, followed by examination of the chromatographic performance. The overall objective is to correlate the processing parameters, the material characteristics and the separation performance. Liquid chromatographic methods are powerful techniques to separate complex mixtures of compounds into their individual constituents. The purpose of this work is to provide an entirely new way to synthesize the materials upon which the separation takes place. Applications of such separations are wide-spread in areas such as environmental analysis, pharmaceutical analysis, and many others. The focus of the project is to make materials with properties superior to those now available.

该项目由Suny-Buffalo助理教授Luis A. Colon指导，得到了化学划分的分析和表面化学计划的支持。 这项工作将使用溶胶 - 凝胶技术合成化学键合的固定相，用于色谱方法，尤其是在开放式和包装柱中的高性能液相色谱（HPLC）和电色谱法。 在制造二氧化硅期间，将所需的官能团掺入Sol-Gel试剂中将产生不进行水解的Si-C键，并提供多层的材料。 这些特征对于解决了在高pH下分离的现有问题的现有问题尤其有希望。将对影响玻璃形成过程中涉及的化学反应的变量进行研究。 许多技术（ESCA，SIMS，FTIR等）将用于检查眼镜的物理化学特性，然后检查色谱性能。 总体目标是将处理参数，材料特征和分离性能相关联。 液相色谱方法是将化合物的复杂混合物分为各个成分的强大技术。 这项工作的目的是提供一种全新的方法来综合分离发生的材料。 这种分离的应用在环境分析，药物分析等领域广泛广泛。 该项目的重点是使材料具有优于现在可用的材料。
