本文报道了一种由熔融石英、聚乙烯和聚(乙烯基)组成的开放式毛细管和水-亲水/疏水有机混合载体溶液组成的毛细管色谱系统。我们称这种系统为管径向分布色谱(TRDC)系统。在本研究中,色谱图中溶质峰的方差、理论塔板数和相当于理论塔板的高度使用从溶质二次矩微分方程导出的理论方程表示。根据理论方程,结合分析条件和实验数据,计算了TRDC体系中毛细管外相的厚度与扩散系数之间的关系。TRDC系统的外相具有比标准液相色谱中的固定相更大的扩散系数和更大的厚度。我们证实了分离性能的基础上获得的管径向分布的载体溶剂在层流条件下的TRDC系统,通过考虑在毛细管中的内相和外相的产生。
A capillary chromatography system that consists of an open capillary tube composed of fused–silica, polyethylene, and poly(tetrafluoroethylene), and a water–hydrophilic/hydrophobic organic mixture carrier solution has been developed. We call this system the tube radial distribution chromatography (TRDC) system. In this study, variance, theoretical plate number, and height equivalent to a theoretical plate for a solute peak in the chromatogram were expressed using theoretical equations derived from the differential equation for the secondary moment of a solute. The relationship between the thickness and diffusion coefficient in the outer phase in the capillary tube in the TRDC system was calculated from theoretical equations using numerical values for the analytical conditions and experimental data. The outer phase that featured the TRDC system had a larger diffusion coefficient and a larger thickness than those of the stationary phase in standard liquid chromatography. We confirmed the separation performance obtained on the basis of the tube radial distribution of the carrier solvents under laminar flow conditions in the TRDC system by considering the inner and outer phase generation in the capillary tube.
