Chemistry: Analytical And Immunological Testing > Including Chromatography Including ChromatographyIncluding Chromatography patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.02/08/07 - 20070031974 - Gas analysis method The present invention provides a method for analyzing gases such as carbon dioxide. Economical on-site analytical capabilities are provided for by concentrating the impurities prior to their analysis. ... 10/26/06 - 20060240564 - Ph gradient ion exchange lc-ms and mass compatible buffers A system for pH gradient ion exchange LC-MS and methods of using such system are described. A buffer system for pH gradient LC-MS that are compatible with a mass spectrometer and methods of using such buffer system are also disclosed. ... 09/21/06 - 20060211125 - Electrolytic eluent generator An acid or base is generated in an aqueous solution by the steps of: (a) providing a source of first ions adjacent an aqueous liquid in a first acid or base generation zone, separated by a first barrier (e.g., anion exchange membrane) substantially preventing liquid flow and transporting ions only ... 06/01/06 - 20060115904 - Partial modulation via pulsed flow modulator for comprehensive two-dimensional liquid or gas chromatography with multiple modulation periods This invention is a method and device for use with multi-dimensional chromatography that utilizes partial modulation with multiple secondary retention times. An analyte-bearing sample is subjected to a first dimension of chromatography. Thereafter the separated analyte-bearing sample is diluted with a modulated second carrier such at the analyte-bearing sample is ... 05/11/06 - 20060099716 - Interface assembly for pre-concentrating analytes in chromatography A system for interfacing a sampling device and a chromatograph and for pre-concentrating analytes in a sample prior to introducing the sample into the chromatographic column is generally disclosed comprising an interface housing with a first channel and an adsorbent housing with a second channel, which contains at least one ... 03/16/06 - 20060057733 - Capillary ion chromatography An apparatus for capillary ion chromatography comprising a suppressor comprising flow-through ion exchange packing in a housing and capillary tubing formed of a permselective ion exchange membrane, and at least partially disposed in said ion exchange packing. Also, a recycle conduit for aqueous liquid from the detector to the packing. ... 12/15/05 - 20050277200 - Method of modulating a second carrier for partial modulation via pulsed flow modulator for comprehensive two-dimensional liquid or gas chromatography This invention is a method and device for use with multi-dimensional chromatography that utilizes partial modulation. An analyte-bearing sample is subjected to a first dimension of chromatography. Thereafter the separated analyte-bearing sample is diluted with a modulated second carrier such at the analyte-bearing sample is not stopped or its temperature ... 12/15/05 - 20050277199 - Single-pass compound purification and analysis The present invention relates to high-throughput compound purification and analysis systems that include representative sample fraction storage components that are structured to at least transiently store representative sample fraction aliquots prior to analysis. In addition, related computer program products and methods are also provided. ... 11/03/05 - 20050244980 - On-line gas chromatographic analysis of airborne particles A method and apparatus for the in-situ, chemical analysis of an aerosol. The method may include the steps of: collecting an aerosol; thermally desorbing the aerosol into a carrier gas to provide desorbed aerosol material; transporting the desorbed aerosol material onto the head of a gas chromatography column; analyzing the ... 10/20/05 - 20050233464 - Methods and apparatus for identifying compounds in a sample Embodiments of the present invention provide methods and apparatus for comparing the proteome and or metabonome of an organism or culture to standard values, over time, or after a change has taken place, a pertubation, with respect to the organinsm or culture. ... 09/29/05 - 20050214949 - Process for producing chemical product and quality inspection process for chemical used in same A process for producing a chemical product from one or more chemicals is provided. The process includes a step of determining in advance a maximum permissible amount of an impurity peak and/or a minimum permissible amount of an effective component peak under given analytical conditions for at least one of ... 08/18/05 - 20050181516 - Bioequivalence determination using expression profiling The present invention provides methods to use expression profiles to determine the bioequivalence of two or more pharmaceutically equivalent drug formulations. In addition, this invention provides methods to select drug formulations that are able to substitute for standard drug formulations without change in clinical efficacy. In other embodiments, this invention ... ### FreshPatents.com Support |
