Title
(EN) ELECTRO-PNEUMATIC DISTRIBUTOR FOR MULTIPLEXED $g(m)-TAS DEVICES
(FR) DISTRIBUTEUR ELECTRO-PNEUMATIQUE POUR DISPOSITIFS A MICROSYSTEMES ANALYTIQUES MULTIPLEXES
Abstract
(EN)
An electrospray system is disclosed. The electrospray system includes a microdevice (10) comprising wells (12), channels (16), and electrospray tips (14); an electro-pneumatic distributor (22) comprising channels (28) and electrodes (24); a supply block (36) comprising gas supply channel (34) and electric conductor (32); and a gasket (18) with holes (20). The distributor is suitable for simultaneous, selective application of pressure and electric current to individual channels of a microdevice.
(FR)
L'invention concerne un système d'électronébulisation, comprenant un microdispositif (10) présentant des cupules (12), des canaux (16) et des pointes d'électronébulisation (14), un distributeur électro-pneumatique (22) présentant des canaux (28) et des électrodes (24), un bloc d'alimentation (36) présentant un canal d'alimentation en gaz (34) et un conducteur électrique (32), ainsi qu'un joint (18) présentant des orifices (20). Le distributeur est conçu pour une application simultanée et sélective de pression et de courant électrique dans les canaux individuels d'un microdispositif.
