摘要： In a liquid chromatograph, the disulfide adsorption of iron atoms in a filter for a column is avoided and thus peak tailing in a chromatogram is prevented to thereby prevent a lowering in the sample recovery rate. A liquid chromatograph column comprising a hollow tubular column body, a bead-shaped packing material which is packed in the hollow part of the column body, a filter provided with a mesh which has a mesh size smaller than the particle diameter of the packing material, and a cap which presses the filter against the packing material to thereby enclose the packing material within the column body, characterized in that the main component of the filter is nickel or hastelloy.

摘要： In a liquid chromatography apparatus, a separation column of intermediate stage is additionally connected between a separation column of first stage and a separation column of second stage. Preferably, a switching unit and a liquid feed unit for mixing and feeding a plurality of solutions are added to improve a separation capability. A three-dimensional liquid chromatography apparatus capable of avoiding the “solution interference” can be realized. Even a complex sample containing a hydrophilic component and a hydrophobic component in a mixed state can be separated and analyzed satisfactorily on-line.

摘要： The invention intends to determine a presence ratio between mixed compounds which are difficult to separate from each other by a separation unit and cannot be discriminated by MS. In a mass spectrometer with an MSn analysis function for ionizing a sample eluted from a separation unit for separating the sample into individual components, fragmenting an ion of a desired mass number, and performing a mass analysis of fragment ions, the mass spectrometer includes a database storing correlation information between an isomer presence ratio and a particular ion intensity ratio in a mass spectrum per isomer. An isomer ratio can be clarified even for a mixed sample of isomers, such as enantiomers, which are difficult to separate from each other by the separation unit and cannot be discriminated by MS.

摘要： A method for analyzing a multi-channel chromatogram is realized for accurately resolving overlapping peaks on a multi-channel chromatogram to permit analysis of the composition of a sample. First, components of overlapping peaks are specified. A data matrix Dij is determined, and compressed in the wavelength direction to obtain a data matrix vector Di. Next, the two-dimensional data is deconvoluted, final standard deviation s0 is registered, and the deconvoluted two-dimensional data is reconvoluted to a retention intensity matrix. A quantitative spectral intensity matrix is computed, components are identified, and the identified components are quantified. Subsequently, an eigenvalue problem is solved, and the number n of components is estimated. The deconvolution and computation of the eigenvalue problem are iteratively executed until the peaks are isolated. Then, elution profiles are calculated, the components are identified, and the identified components are quantified.

摘要： In a database MSn spectrum search, search of a known compound whose principal chain is identical to that of an unknown compound is enabled, thereby allowing analysis of an entire structure even if the entire structures of the known compound in database and that of the measured unknown compound are not identical. The MSn spectrum obtained in the MSn measurement of the unknown compound is compared with all the MSm spectra (m≧1) in the database regardless of MSn generation. In the MSn measurement of a series of related compounds including various types of different side chains of the same principal chain, such as in the case of biopolymers, it becomes possible to determine the structure of the principal chain using a database search even if the entire structure is not clear. And the estimation of the entire structure is made possible on the basis of the principal chain structure.
