Patent number: 6610978Abstract: The present invention relates to microdevices for introducing a small volume of a fluid sample into an ionization chamber. The microdevices are constructed from a substrate having a first and second opposing surfaces, the substrate having a microchannel formed in the first surface, and a cover plate arranged over the first surface, the cover plate in combination with the microchannel defining a conduit for conveying the sample. A sample inlet port is provided in fluid communication with the microchannel, wherein the sample inlet port allows the fluid sample from an external source to be conveyed in a defined sample flow path that travels, in order, through the sample inlet port, the conduit and a sample outlet port and into the ionization chamber. Optionally, the fluid sample undergoes a chemical or biochemical reaction within an integrated portion of the microdevice before reaching the ionization chamber. A nebulizing means nebulizes the fluid sample in a nebulizing region adjacent to the sample outlet port.Type: GrantFiled: March 27, 2001Date of Patent: August 26, 2003Assignee: Agilent Technologies, Inc.Inventors: Hongfeng Yin, Thomas P.

Patent number: 6033628Abstract: In a method of forming a microchannel and/or microcavity structure by bonding together two elements (1, 2) having opposed plane surfaces of the same or different material, one or both surfaces having open channels and/or cavities, bonding is effected by applying to one or both element surfaces (1, 2) a thin layer (3) of a solution of a material capable of fusing with and having a lower melting point than that of the material or materials of the two element surfaces (1, 2) in a solvent which substantially does not dissolve the element surface material or materials. The solvent is then removed, and the two elements (1, 2) are brought together and heated to a temperature where the dissolved material is caused to melt but not the element surface material or materials.Type: GrantFiled: April 27, 1998Date of Patent: March 7, 2000Assignee: Agilent Technologies, Inc.Inventors: Patrick Kaltenbach, Sally A.
