An electrophoresis chip that can be small and simple and that can analyze a sample with high accuracy is provided. The electrophoresis chip includes an upper substrate 4, a lower substrate 1, an introduction reservoir 2a, a recovery reservoir 2b and a capillary channel for sample analysis 3x.
The introduction reservoir 2a and the recovery reservoir 2b are formed in the lower substrate 1. The introduction reservoir 2a and the recovery reservoir 2b are in communication with each other via the capillary channel for sample analysis 3x. The introduction reservoir 2a receives a sample to be measured.
The sample is electrophoretically introduced directly into the capillary channel for sample analysis 3x by creating a potential difference between the introduction reservoir 2a and the recovery reservoir 2b, and is also analyzed in the capillary channel for sample analysis 3x during the separation of the sample while the sample is being continuously supplied.
本发明提供了一种体积小、结构简单并能对样品进行高精度分析的电泳芯片。电泳芯片包括上基板 4、下基板 1、导入槽 2a、回收槽 2b 和用于样品分析的毛细管通道 3x。
导入槽 2a 和回收槽 2b 形成于下基板 1 中。导入贮液器 2a 和回收贮液器 2b 通过用于样品分析的毛细管通道 3x 相互连通。导入槽 2a 接收待测样品。
通过在引入贮液器 2a 和回收贮液器 2b 之间产生电位差,以电泳方式将样品直接引入用于样品分析的毛细管通道 3x,并在连续供应样品的过程中,在用于样品分析的毛细管通道 3x 中对样品进行分析。
