MICROCHANNEL DEVICE AND METHOD PERTAINING THERETO

摘要

Provided are a microchannel device for realizing an effective manipulation of a tiny amount of liquid and a method relating thereto . A microchannel device (1) includes: an upstream channel portion (10) configured to allow an upstream liquid plug and a gas to flow therethrough; a downstream channel portion (20) configured to allow a downstream liquid plug and a gas to flow therethrough; a liquid holding portion (30) provided between a downstream end portion of the upstream channel portion and an upstream end portion of the downstream channel portion, the liquid holding portion being configured to hold a main liquid plug therein; and a gas bypass channel portion (40) provided so as to bypass the liquid holding portion from the downstream end portion of the upstream channel portion to the upstream end portion of the downstream channel portion, the gas bypass channel portion being configured to allow the gas to flow therethrough in a state in which the liquid holding portion holds the main liquid plug.
