US Patent:

20040018611, Jan 29, 2004
Filed:

Jul 23, 2002
Appl. No.:

10/202462
Inventors:

Michael Ward - Los Alamos NM, US
Piotr Grodzinski - Chandler AZ, US
Robin Liu - Chandler AZ, US
Bradley Engel - Chandler AZ, US
Yingjie Liu - Chandler AZ, US
International Classification:

C12M001/34
G01N033/553
US Classification:

435/287200
Abstract:

The present invention provides microfluidic devices that can be used to effect a number of manipulations on a sample to ultimately result in target analyte detection or quantification. The device provides at least one magnetic microchannel that is capable of separating magnetic or magnetically-labeled target analytes from non-magnetic materials. Further, a magnetic microchannel may sort materials according to their magnetic response. Alternatively, magnetic or magnetically-labeled components other than the target analytes can be retained by the magnetic microchannel and are thus removed from the target analytes. Depending on the specificity of the binding ligand, one can either separate a vast population of analytes sharing a common binding motif, or specifically retain a rare target analyte because of its recognition of a specific ligand on the magnetic particle.

US Patent:

20110197655, Aug 18, 2011
Filed:

Dec 7, 2010
Appl. No.:

12/962376
Inventors:

Cynthia G. Briscoe - Tempe AZ, US
Huinan Yu - Kildeer IL, US
Piotr Grodzinski - Rockville MD, US
Rong-Fong Huang - Fremone CA, US
Jeremy W. Burdon - Minneapolis MN, US
Nicholas J. Naclerio - Menlo Park CA, US
David Wilcox - Sun Lakes AZ, US
Assignee:

WATERS TECHNOLOGIES CORPORATION - Milford MA
International Classification:

G01N 30/02
US Classification:

73 2339
Abstract:

A micro-gas chromatograph column is formed by texturing a channel into a plurality of green-sheet layers, which are then sintered together to form a substantially monolithic structure. A thick-film paste may be added to the channel textured in the green-sheet layers to provide a porous plug sintered in the micro-gas chromatograph column in the substantially monolithic. A thermal conductivity detector is formed in the substantially monolithic structure by depositing a conductive thick-film paste on the surface of one of the green-sheet layers to define a resistor in an exit channel of the micro-gas chromatograph column.
