摘要

本研究讨论了用微流控装置进行组分分离。基于分离原理，采用了一种在螺旋通道内由离心力产生外力的方法。在本研究中，使用了4种不同粒径的聚苯乙烯颗粒，粒径范围在1-45µm之间，并对每种粒径的分离性能进行了评价。离心力随通道内流速的增大而增大;但是，这次测试的流量是一个固定的输入参数，为100µL/min。高速相机微通道观测结果表明，颗粒密度可能是导致分离效率下降的一个因素。因此，通过在三种不同的颗粒密度下进行测试，我们能够实验地研究基于颗粒大小和密度的分离效率的变化。在本研究中，我们考虑了颗粒直径的大小和密度对分离效率的影响，并将其应用于现场式分离装置。

Analysis of Separation Efficiency Focusing on Particle Concentration and Size Using a Spiral Microfluidic Device

This study discusses component separation using a microfluidic device. Based on the separation principle, a method was adopted to generate an external force due to centrifugal force in a spirally designed channel. In this study, four types of polystyrene particles with different diameters ranging within 1–45 µm were used, and the separation performance was evaluated for each particle size. The centrifugal force increased as the flow velocity in the channel increased; however, this time, the test was conducted with the flow rate, which is an input parameter fixed at 100 µL/min. The results of the micro-channel observation using a high-speed camera indicated that the particle density might be a factor in the decrease in separation efficiency. Therefore, by conducting tests at three different particle densities, we were able to experimentally investigate the change in separation efficiency based on the particle size and density. In this study, we considered the separation efficiency due to the size and density of the particle diameter along with its application to an onsite-type separation device.
