Microfluidic system

Abstract

A dual-side field-emission display has one cathode plate and two anode plates. The cathode plate has two opposite surfaces, and each surface has a cathode conductive layer and an electron emission layer formed thereon. The anode plates are disposed at two opposing sides of the cathode plate. Each of the anode plates has an anode conductive layer and a phosphor layer.

1 . A method for presenting an analyte of a liquid sample as an MS-analyte to a mass spectrometer, characterized 
 (a) in comprising the steps of: 
 (i) applying a liquid sample containing the analyte to a sample inlet port of a microchannel structure of a microfluidic device, said structure also comprising an outlet port (MS-port) that is capable of being interfaced with a mass spectrometer,  
 (ii) passing the analyte to the MS-port thereby transforming it to an MS-analyte, and  
 (iii) presenting the MS-analyte to mass spectrometer via the MS-port, and  
   (b) in inertia force being used for liquid transportation within at least a part of said microchannel structure.
