Method for controlling liquid transport in flow path of biomolecule analyzer using computer, and biomolecule purification system

A biomolecule purification system comprising:

• a biomolecule analyzer having a flow path;
• and
• a computer configured to control liquid transport in the flow path, wherein
• the biomolecule analyzer includes:
• a first chamber that stores a first liquid;
• a second chamber that stores a second liquid;
• a waste liquid chamber;
• and
• a membrane chamber having a purification membrane and disposed between the first chamber and the second chamber and the waste liquid chamber, and
• the computer is configured to execute:
• controlling transport of the second liquid until the second liquid exceeds at least a junction between a first flow path leading from the first chamber to the waste liquid chamber and a second flow path extending from the second chamber, and discharging a fluid different from the first and second liquids from the second flow path;
• controlling transport of the first liquid from the first chamber to the waste liquid chamber via the membrane chamber;
• and
• controlling transport of the second liquid in the second chamber from the second chamber to the waste liquid chamber via the membrane chamber.
