基于显微镜光学和电荷耦合器件相机的成像系统被用来在狭窄的熔融二氧化硅毛细管内形成高分辨率的液核图像。该技术允许在电动和流体(泊松)条件下直接检查毛细管内的流体运动。描述了两个实验。第一种方法是在荧光标记的溶剂通过毛细管时监测它的前端。第二种是使用亚微米大小的粒子作为探针来检测局部速度。在毛细管电泳带展宽的背景下，对结果进行了讨论
An imaging system based on microscope optics and a charge-coupled device camera is used to form high-resolution images of the liquid core inside narrow fused-silica capillaries. This technique allows direct examination of the fluid motion inside the capillary under electrokinetic and hydrodynamic (Poiseuille) conditions. Two experiments are described. The first involves monitoring the front of the fluorescence-labeled solvent as it travels through the capillary. The second is an examination of the local velocities using submicron-sized particles as probes. The results are discussed in context of band broadening in capillary electrophoresis
