    摘要： The present invention relates to evaporation apparatus (100) comprising manifolds provided with at least one nozzle (102), a tank unit (103) for a liquid, and a sample holder configured to be inserted into the tank unit. The sample holder is configured to hold at least one sample in a defined position relative the at least one nozzle a control unit (104) an inlet port (105) configured to be connected to a gas supply, a pressure regulator (106) arranged downstream the inlet port (105). A set value of the pressure regulator (106) is controlled by the control unit (104), a control valve (107) arranged downstream the pressure regulator (106), wherein each of the at least one manifold (101a-d) is connected to a corresponding output port of the control valve. The control valve is controlled by the control unit (104), and the control unit is configured to set the set value of the pressure regulator to a value that causes a predetermined gas flow from each of the at least one nozzle.

    摘要： The present invention is a method for automated mass-directed separation of two or more components from a sample, which method comprises defining a solvent gradient by its changing composition; subjecting said solvent gradient to mass spectrometry (MS) to generate gradient signal(s); passing a gradient including at least part(s) of the defined gradient across a packed chromatography column to which a sample has been applied; subjecting the eluent exiting said column to MS to generate sample signal(s); generating a spectrum by subtracting the gradient signals from the sample signals across a selected range of m/z values; and directing a fraction collector to collect fraction(s) each comprising a separated component based on the spectrum generated.

    摘要： A micro vial assembly for performing microwave-assisted chemical reactions on small reaction mixture volumes is disclosed, wherein a reaction vessel (10) is sealed through a diaphragm (30) that is capped over an open end of the reaction vessel. The reaction vessel mouths in an end plane of a sleeve (20) surrounding the reaction vessel, the diaphragm being clamped for sealing the open end of the vessel by means of a cap (40) which is secured to the sleeve. The sleeve provides a radial extension of the reaction vessel in order to bridge the radial distance between a wall of the reaction vessel and other components in a system for performing microwave-assisted chemical reactions.

    摘要： The present invention provides a method of identifying a base at a target position in a sample nucleic acid sequence, said method comprising: subjecting a primer hybridised to said sample nucleic acid immediately adjacent to the target position, to a polymerase primer extension reaction in the presence of a nucleotide, whereby the nucleotide will only become incorporated if it is complementary to the base in the target position, and determining whether or not said nucleotide is incorporated by detecting whether PPi is released, the identity of the target base being determined from the identity of any nucleotide incorporated, wherein, where said nucleotide comprises an adenine base, an α-thio triphosphate analogue of said nucleotide is used, ant the Rp isomer of said analogue and/or the degradation products of said analogue are eliminated from the polymerase reaction step.

    摘要： The present invention relates to a method of conditioning a dry-packed chromatography column, which method comprises providing a column packed with inert and hydrophilic chromatography resin; and driving a solvent or solvent mix across the column. The solvent(s) are selected to be less hydrophilic than the chromatography resin; and the rate of the solvent flow is controlled to a rate which does not cause the system pressure to exceed a predefined threshold. The present invention is advantageously used in FLASH chromatography, where the generation of heat may pose problems e.g. to plastic frits or filters at high flow rates and/or wetting of dry resins.
