摘要： It is possible to correctly determine whether a change in the pressure or flow rate is caused by normal opening and closing operations of a check valve and to monitor in real time whether an operation of a check valve is normal or abnormal in a liquid supply device. Light is introduced in the check valve and a change in the quantity of light transmitted through or reflected by the check valve, caused by the opening and closing of the valve is detected, so that the opening and closing operations of the check valve can be directly detected. The check valve is arranged in a pipe in the liquid supply device, and a change in the pressure in the pipe is monitored on the basis of a signal from a pressure sensor and a signal which represents the opening and closing of the check valve.

摘要： In a liquid delivery device, when an inlet-side check valve and an outlet-side check valve of a first cylinder are both closed, and compression of an eluent inside the first cylinder is started by means of a first plunger inside the first cylinder, a control unit doubles the rotational speed of a step motor, and measures the amount of change in the pressure inside the first cylinder which changes for a prescribed time by means of a first cylinder internal pressure detector. The time elapsed until the pressure inside the first cylinder is the same as the pressure inside a discharge-side flow passage is predicted using the rate of change over time of the pressure of the eluent. When the predicted elapsed time has elapsed, the rotational speed of the step motor is returned to the original speed, and the compression of the eluent inside the first cylinder is completed.

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.
