摘要： A method for extracting at least one target compound from a sample includes injecting an overloaded amount of the sample into a chromatographic conduit (110), and flowing a solvent having a time-varying composition through the conduit (110). An apparatus for extracting at least one target compound from a sample includes a chromatography module, a mass-spectrometry module in fluid communication with the chromatography module to receive a portion of an eluent from the chromatography module, and a control unit in communication with the chromatography module and the mass-spectrometry module.

摘要： A device for limiting sample evaporation. The device has a vessel body having a body exterior surface and at least one body interior surface. The at least one body interior surface has one or more walls defining a first chamber, a second chamber and a conduit means. The first chamber has a first chamber opening for receiving at least one of the groups selected from a sample and a sample dispensing device. The first chamber opening defines the border of the body exterior surface and the body interior surface. The conduit means is in communication with the first chamber and the second chamber for receiving at least one of the group consisting of sample from said first chamber, a sample from a sample dispensing device and a sample dispensing device passing through or into the conduit means for placing the sample in the conduit means or into the second chamber. The second chamber is in communication with the conduit means for receiving and containing the sample from at least one of the group selected from the sample dispensing device and conduit means. The conduit means is arranged such that the sample in the second chamber is substantially isolated from the atmosphere to limit sample evaporation in the second chamber as the sample is contained therein.

摘要： The present invention provides methods for enhancing chemical reactions of molecules, e.g., biomolecules, with destructible surfactants. The chemical reactions may involve and/or be associate with analysis, e.g., solubilizing, separating, purifying and/or characterizing the molecules. In one aspect, the anionic surfactants of the present invention may be selectively broken up at relatively low pH. The resulting breakdown products of the surfactants may be removed from the molecule/sample with relative ease. The invention has applicability in a variety of analytical techniques.
