Abstract

Un sistema (10) de laboratorio de microchip y un método suministran manipulaciones de fluido para una variedad de aplicaciones, que incluyen la inyeccion de muestras para las separaciones químicas por microchip. Este microchip se fabrica usando procedimientos fotolitográficos estándar y el grabado químico en humedo, con el substrato y la placa de cubierta unidos usando el enlace directo. Se llevan a cabo la electroforesia capilar y la electrocromatografía en los canales (26, 28, 30, 32, 34, 46, 38) formados en el substrato. Se cargan los analitos (muestras que se van a analizar) en una interseccion de canales, de cuatro vías, bombeando electrocinéticamente el analito a través de la interseccion (40), seguido por un cambio de los potenciales, para formar un tapon del analito dentro del canal (34) de separacion.
