Abstract

The invention provides a flow control mechanism for microchip. A compressed gas is supplied from above a sample container whose upper part is open. A transfer flow path to a reaction container is provided at a lower part and a transfer flow path from the reaction container is provided at an upper part. Transfer means is provided outside a microchip so that the compressed gas is supplied from a member (cover) holding the microchip.

Description

technical field [0001] The present invention relates to a fluid control mechanism for a microchip, in particular to a plurality of reaction tanks and sample tanks used for reaction / mixing / separation / analysis of chemical samples, or gene analysis, etc. A micro analysis chip between the reaction tank and the sample tank. Background technique [0002] In recent years, as recorded in Zhuangzi Xiyi's "Biochemical Microchemical Analysis System Micromachine Technology" (non-patent document 1) or JP-A-2002-214241 (patent document 2), in microreactors, microarrays and known as " There are more and more studies on gene analysis by reacting samples or liquid samples on a tiny chip of "Lab on a chip", and studies have been made on the mechanism of sequentially transporting a small amount of liquid samples or the mechanism of controlling a small amount of liquid samples. [0003] Non-Patent Document 1, as "2. μTAS using micromechanical components", discloses [a sample introduction mecha...
