Abstract
A capillary electrophoresis system has a sample tube from which a sample is injected into a capillary tube by introducing a gas thereinto through an on-off valve. In order to maintain its internal pressure constantly at a target level, the pressure inside the sample tube is monitored after the valve is closed, and the period of time during which the valve is opened is adjusted according to the difference between the maximum level, to which the internal pressure reaches, and an upper limit value predefined above the target level.
