Filed:

Aug 30, 2005

Appl. No.:

11/216884

Inventors:

Reid Brennen - San Francisco CA, US
Tom van de Goor - San Mateo CA, US
Gangqiang Li - Palo Alto CA, US
Kevin Killeen - Woodside CA, US

International Classification:

H01J 49/10

US Classification:

250288000

Abstract:

The invention described herein provides a mass spectrometry system, having an ion source including an ionization device for producing ions, a collection conduit adjacent to the ionization device for collecting ions produced by the ionization device, a first gas source for supplying gas to desolvate ions produced by the ionization device, a second gas source for supplying gas at a defined flow to the ionization region, and a detector downstream from the ion source for detecting ions produced by the ion source. The invention also provides an ion source including an ionization device for producing ions, a collection conduit adjacent to the ionization device for collecting ions produced by the ionization device, a first gas source for supplying gas to desolvate ions produced by the ionization device, and a second gas source for supplying gas at a defined flow to the ionization region. A method for producing analyte ions is also disclosed. The method includes producing analyte ions from an ionization device, directing a first heated gas toward the analyte ions to desolvate the analyte ions, and directing a second gas toward the analyte ions at a defined and continual flow rate.

International Classification:

G01R 27/08
G01N 30/64

US Classification:

324695, 73 6158

Abstract:

A contactless detection cell () for detecting an electrical property of one or more sample compounds in a flow path is described. The contactless detection cell () comprises a transmitter electrode () adapted for capacitively coupling an AC current into a detection channel () of the flow path, and a receiver electrode () adapted for receiving the AC current that has been coupled into the detection channel (). An inner cross-section (ID) in at least a section of the detection channel is different than an inner cross-section (ID) of the flow path () towards the detection channel ().

Abstract:

A device for mixing fluids is provided. The device is comprised of a substrate containing a first mixing feature that terminates at a first opening located on a surface of the substrate and a cover plate containing a second mixing feature that terminates at a second opening located on a surface of the cover plate. Also provided is a means for producing relative sliding motion between the cover plate and substrate surfaces. The substrate and cover plate surfaces are maintained in fluid-tight contact with each other such that relative sliding motion between the first and second mixing features induces fluid mixing through the first and second openings when fluid is present in the mixing features. Also provided is a method for mixing fluids. The device and method are particularly suited for microfluidic applications.
