Title:

MICROFLUID DEVICE WITH SAMPLE INJECTOR, AND METHOD

Document Type and Number:

Japanese Patent JP2008209407

Kind Code:

A

Abstract:

To provide a microfluid device and a system which are controlled for attaining various desirable sample injection characteristics.

The system is employed for injecting a liquid sample into an electrolyte channel inside a microfluid device that has a channel network, and the channel network includes an electrolyte channel having upstream and downstream channel portions and a first side channel, a second side channel, and a third side channel. The first side channel, the second side channel and the third side channel intersect the electrolyte channel between the two channel portions respectively at a first port, a second port, and a third port; at least one port has an axial section, crossing the electrolyte channel between the two channel sections; and here, at least one of the ports has a gap spaced in the axial direction, from the other two ports along the electrolyte.
