Title (EN) METHOD OF ENRICHING LIQUID PHASE INSIDE MICRO CHIP BY GAS-LIQUID TWO-PHASE FLOW AND MICRO CHIP DEVICE THEREFOR
(FR) PROCEDE D'ENRICHISSEMENT D'UNE PHASE LIQUIDE A L'INTERIEUR D'UNE MICROPUCE PAR ECOULEMENT DIPHASE GAZ-LIQUIDE ET DISPOSITIF A MICROPUCES ASSOCIE
Abstract: front page image
(EN)A method of enriching liquid phase inside a micro chip having a flow passage formed in the substrate thereof, comprising the steps of forming a boundary face in the flow passage by a gas-liquid two phase flow for enriching the liquid phase, wherein an enriching method followed by a volumetric change is integrated in the micro chip, whereby the liquid phase can be enriched at a high efficiency.
(FR)L'invention concerne un procédé permettant d'enrichir une phase liquide à l'intérieur d'une micropuce ayant un passage d'écoulement formé dans son substrat, qui consiste à former une face limite dans ledit passage par un écoulement diphasé gaz-liquide destiné à enrichir la phase liquide, le procédé d'enrichissement, suivi d'un changement volumétrique, étant intégré dans la micropuce et la phase liquide pouvant être enrichie de manière très efficace.
