<p>A chip (400) is composed of a substrate (401), and a frame part (402) arranged on the surface of the substrate (401) in contact with the substrate (401). A flow channel (102), which is to be a groove-type flow channel for electrophoresis of a sample to be mass-analyzed, has the substrate (401) as a bottom surface, and the frame part (402) as a side wall. The substrate (401) and the frame part (402) can be separated.</p> |
