Miniaturized Device For Separating The Constituents Of A Sample And Delivering The Constituents Of The Separated Sample To A Mass Spectrometer

View page
US Patent:
6459080, Oct 1, 2002
Filed:
Jun 2, 1999
Appl. No.:
09/324344
Inventors:
Hongfeng Yin - San Jose CA
Sally A Swedberg - Palo Alto CA
John A Chakel - San Mateo CA
Assignee:
Agilent Technologies, Inc. - Palo Alto CA
International Classification:
H01J 4900
US Classification:
250288, 250281, 250282, 1562728, 156290, 156292, 2101982
Abstract:
âA miniaturized planar device is described for use in a liquid phase analysis system. The device comprises a separation compartment that is in fluidic communication with a make-up flow channel and a channel compartment that terminates in an on-device mass spectrometer delivery means. The device is formed by microfabrication of microstructures in novel support substrates. â.

Integrated Planar Liquid Handling System For Maldi-Tof Ms

View page
US Patent:
57058130, Jan 6, 1998
Filed:
Nov 1, 1995
Appl. No.:
8/548349
Inventors:
James A. Apffel - Palo Alto CA
John A. Chakel - San Mateo CA
William S. Hancock - Hillsborough CA
Kay Lichtenwalter - San Jose CA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
H01J 4904
US Classification:
250288
Abstract:
An integrated liquid sample handling system for matrix-assisted laser-desorption/ionization time-of-flight mass spectroscopy (MALDI-TF MS) is described. The integrated system comprises a miniaturized sample handling compartment containing a MALDI ionization surface for separating, chemically manipulating and detecting analytes by MALDI -TOF MS. The miniaturized integrated sample handling system disclosed herein is applicable to a wide range of analytical problems that require separation and/or chemical manipulation of a sample prior to mass analysis as part of the analytical procedure.

Integrated Nucleic Acid Analysis System For Maldi-Tof Ms

View page
US Patent:
57168253, Feb 10, 1998
Filed:
Nov 1, 1995
Appl. No.:
8/551501
Inventors:
William S. Hancock - Hillsborough CA
John A. Chakel - San Mateo CA
James A. Apffel - Palo Alto CA
Kay Lichtenwalter - San Jose CA
Assignee:
Hewlett Packard Company - Palo Alto CA
International Classification:
C12M 138
C12M 140
US Classification:
4352865
Abstract:
An integrated nucleic acid sample analysis system for matrix-assisted laser-desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF MS) is described. The integrated system comprises a miniaturized sample preparation compartment interfaced directly with a MALDI-TOF ionization surface for amplifying and/or otherwise chemically manipulating an oligonucleotide analyte and presenting the analyte to a MALDI ionization surface for mass spectrometry analysis. The miniaturized integrated sample handling system disclosed herein finds application in the amplification and analysis of DNA samples for genetic diagnosis and other uses.
