Problems solved by technology

[0010] In addition, in the micro-comprehensive analysis chip, since the cross-sectional size of the flow path is very small, the influence of the interaction such as the capillary force between the inner wall surface of the flow path and the fluid is large.
This force is easily affected by the surface state of the inner wall of the flow path (surface roughness or surface deposits, etc.). The correct split ratio, including a split ratio of 1:1, necessitates some new countermeasures

Abstract

A micro total analysis chip including: a main flow path for feeding a liquid; and a divided flow path branched into a plurality of divided paths for dividing and feeding the liquid fed from the main flow path at a predetermined division ratio, wherein a ratio of flow path resistance between each of the divided paths is approximately equal to a reciprocal of the predetermined ratio with which the liquid is divided and fed to the each of the divided paths.

Description

technical field [0001] The present invention relates to a micro-comprehensive analysis chip and a micro-comprehensive analysis system, in particular to a micro-comprehensive analysis chip and a micro-comprehensive analysis system having a plurality of branch flow paths, the branch flow paths are used to transfer liquids such as test bodies or reagents into The specified split ratio is divided and conveyed. Background technique [0002] In recent years, through the use of micro-motor technology and ultra-precision processing technology, existing devices and mechanisms (such as pumps, valves, flow paths, sensors, etc.) for sample preparation, chemical analysis, and chemical synthesis have been developed. A micro-comprehensive analysis chip that is refined and integrated on one chip. [0003] The micro comprehensive analysis chip is also called μ-TAS (Micro total Analysis System: micro total analysis system), bioreactor, chip laboratory (Lab-on-chips), biochip, and is expected...
