Abstract: The present disclosure generally relates to devices and methods for effecting epitachophoresis. Epitachophoresis may be used to effect sample analysis, such as by selective separation, detection, extraction, and/or pre-concentration of target analytes such as, for example, DNA, RNA, and/or other biological molecules. Said target analytes may be collected following epitachophoresis and used for desired downstream applications and further analysis.

Abstract: The present disclosure generally relates to systems comprising devices for effecting epitachophoresis and sample detection and methods of using such systems. Epitachophoresis may be used to effect sample analysis, such as by selective separation, detection, extraction, and/or pre-concentration of target analytes such as, for example, DNA, RNA, and/or other biological molecules. Sample detection may be used to trigger automated target analyte collection. Said target analytes may be used for desired downstream applications and further analysis.

Abstract: A modular multiple lane or capillary electrophoresis (chromatography) system that permits automated parallel separation and comprehensive collection of all fractions from samples in all lanes or columns, with the option of further on-line automated sample fraction analysis, is disclosed. Preferably, fractions are collected in a multi-well fraction collection unit, or plate. The multi-well collection plate is preferably made of a solvent permeable gel, most preferably a hydrophilic, polymeric gel such as agarose or cross-linked polyacrylamide.

Abstract: While the present invention has been described in conjunction with a preferred embodiment, one of ordinary skill, after reading the foregoing specification, will be able to effect various changes, substitutions of equivalents, and other alterations to the compositions and methods set forth herein. It is therefore intended that the protection granted by Letters Patent hereon be limited only by the definitions contained in the appended claims and equivalents thereof.

Abstract: A sample load and injection device (10) includes sample introduction capillaries (11) attached to a microfluidic device (12). Sample introduction capillaries (11) are connected to sample introduction channels (18). Sample introduction capillaries (18) are connected to separation channels (20) at connection points (21). At a defined distance along the separation channels (20), auxilliary channels (23) originate at connection points (24). The sample load and injection device includes cover plate (28) which has connecting channels (26, 32). Connecting channel (26) is associated with ends (24) of sample introduction channels (18). Connecting channel (32) is associated with ends (20).

Abstract: A thermostat array including an array of two or more capillary columns (10) or two or more channels in a microfabricated device is disclosed. A heat conductive material (12) surrounded each individual column or channel in array, each individual column or channel being thermally insulated from every other individual column or channel. One or more independently controlled heating or cooling elements (14) is positioned adjacent to individual columns or channels within the heat conductive material, each heating or cooling element being connected to a source of heating or cooling, and one or more independently controlled temperature sensing elements (16) is positioned adjacent to the individual columns or channels within the heat conductive material. Each temperature sensing element is connected to a temperature controller.

Abstract: A universal interface for continuous on-line liquid sample introduction directly to the time-of-flight mass spectrometer, which can further promote throughput and utility of MALDI-TOF MS, is disclosed. Preferably, the liquid sample includes a matrix, either solid or liquid, for use in matrix-assisted-laser-desorption-ionization, most particularly in a time-of-flight mass spectrometer which can further promote throughput and utility of MALDI-TOF MS. In the method of the invention, the same samples and matrices, both solid and liquid, can be used as in conventional MALDI. In practice of the method of the invention, a solution of sample containing, e.g., peptide and matrix is infused directly into the source chamber of a mass spectrometer at subatmospheric pressure, deposited on a moving sample holder, such as a rotating quartz wheel, and desorbed by, e.g., a nitrogen laser. The method of the invention is particularly amenable to multiplexing, the parallel deposition of multiple samples, e.g.
