Abstract:
1. An electrophoresis chip, said electrophoresis chip being provided with a channel that is filled with a solution in which a sample is dissolved, and said electrophoresis chip being configured to implement electrophoresis by applying voltage along said channel in a state in which said channel is hermetically sealed to separate said sample in said channel, and after said electrophoresis is performed, to carry out mass spectrometry of said sample by scanning a laser along said channel in a state in which said channel is open to an environment in which gas is present; wherein a pattern for holding said solution as droplets being formed on the bottom surface of said channel; and said pattern being made into a pattern in which a first hydrophilic area is surrounded by at least a second hydrophilic area in which the hydrophilic property is lower than that of said first hydrophilic area.
