    摘要: A reference sample having a known concentration is injected into a chromatograph system before an unknown sample is analyzed. This is for the purpose of checking the deterioration of system performance or in other words for the purpose of checking system suitability. In the present invention, the chromatographic characteristic of the check sample at the time of deterioration of the system suitability is expected and stored in a memory in advance to be related to factors of deterioration of system suitability. A factor of deterioration is deduced by comparison between the actually analyzed chromatographic characteristic of the check sample and the relational data stored in the memory. A guidance required for removing the factor is displayed. Disclosed are preferred embodiments of a chromatograph system suitable for analyzing catecholamine or glycated hemoglobin.

    摘要: A liquid chromatograph and chromatography which can perform analysis at a higher speed with clearer separation between peaks. The liquid chromatograph comprises a separation column (10), a buffer pump (7) for feeding a plurality of buffers 1, 2, 3 and 4 into the separation column (10), a sampler (9) disposed in a flow path between the buffer pump (7) and the separation column (10) for introducing a sample to be analyzed into the flow path, and a reaction coil (14) for mixing and then reacting amino acids separated by the separation column (10) with a ninhydrin reagent. The separation column is sized so that a ratio (L1/R) of its length L1 to its inner diameter R is not more than 10. The particle size of an ion exchange resin filled in the separation column (10) is selected to be not more than 4 .mu.m.

    摘要: A sugar chain synthesizer comprising one or more reaction columns packed with immobilized glycosyltransferase and/or glycosidase; one or more separation means, arranged downstream from the reaction columns, for separating reaction products, unreaction products and byproducts contained in the solution eluted from the reaction columns; a first pump for feeding a primer of water soluble polymer and buffer solution to the reaction columns through a first selector valve; a second pump for feeding a buffer solution and sugar nucleotide solution to any one of the reaction columns through a second selector valve; one or more circulation flow paths connecting between a flow path downstream from the separation means and a flow path upstream from each of the reaction columns; and a third selector valve, arranged between the separation means and one or more circulation flow paths, for selective connection between the separation means and a desired circulation flow path. This synthesizer ensures continuous and automatic synthesis of sugar chains even if complicated.

    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: Deterioration of performance of a separation column for liquid chromatograph due to changes in the functional groups during the preservation or application is prevented by filling a solution containing a component in the molecule with the same structure as that of the chemical function group of a packing material for the separation column as a filling liquid together with the packing material in the separation column, and also by washing the separation column with the same filling liquid as a washing solution after the analysis and retaining the washing solution therein, whereby the preservation stability of the separation column is improved and the separation column can be preserved at room temperature.
