摘要： The present invention provides a separation column and a liquid chromatograph using the separation column, which are capable of carrying out a high-speed analysis under high pressure and without a reduction in separation performance of the separation column. In the separation column, a sample and a mobile phase are introduced into a packing material. The chromatograph has a covering member for covering an outer surface of the packing material and a supporting member having the packing material covered with the covering member inserted therein, wherein the level of pressure generated within a gap located between the covering member and the supporting member on the outflow side of the gap, where the fluid is introduced, is lower than that of pressure generated within the gap on the inflow side of the gap, where the fluid flows out of the gap.

摘要： A chromatographic analyzer is provided for facilitating curve fitting by means of the linear least-square method for a chromatogram that contains a plurality of overlapping peaks. The present invention is characterized by a chromatographic data processor for executing data processing of a chromatogram obtained by separating a sample to be measured using a column and detecting the separated sample, wherein fitting processing is executed to each peak in an arbitrary time region having the plurality of peaks of the chromatogram starting from the front side of the time region or from the back side of the time region, and the processed peaks are subtracted from the chromatogram in the time region so that the plurality of peaks in the chromatogram can be separated from one another. Thus, the plurality of overlapping peaks, particularly three or more overlapping peaks in the chromatogram can be easily separated from one another only by defining some setting conditions.

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.
