Abstract

L'invention concerne un procédé et un système permettant de préconcentrer des analytes au niveau d'une microvalve dans un dispositif microfluidique (1600). Le système comprend un canal d'échantillon (1610) chargé avec une solution d'échantillon. Le canal d'échantillon (1610) comprend une microvalve à membrane semiperméable (1630). Un potentiel électrique est appliqué au niveau ou au travers de la microvalve pour préconcentrer la solution d'échantillon lorsque la microvalve est fermée. Une solution d'échantillon est ensuite injectée dans le canal de séparation (1640,2105). Une extrémité capillaire conique (2110) est insérée dans le canal de séparation (2105). L'invention concerne également des procédés comprenant des prétraitements du dispositif ou de la valve pour la préconcentration d'analytes. Pour la préconcentration d'analytes anioniques, le dispositif est cuit. Pour la préconcentration d'analytes cationiques, la surface de la microvalve à membrane (1630) est enduite d'un revêtement polycationique, et le dispositif est cuit.
