Provided is a chromatography mass spectrometry capable of peak detection that can deal with a wide concentration range of a sample component and providing an evaluated value for the result. A plurality of samples having different known concentrations of a component are measured to detect a start point, an apex, and an end point of a peak. Regarding the start point, the apex, and the end point of the detected peak, an evaluated value such as probability is provided as a score to determine a score function. A component having an unknown concentration is measured to detect a start point, an apex, and an end point of a peak. Regarding the start point, the apex, and the end point of the detected peak, the score function is applied to evaluate peak detection results, and a result having a high evaluated value is selected as a peak.

Provided is a method for measuring the concentration of aliphatic hydroxy oxime and neodecanoic acid using gas chromatography. The method includes the steps of: (a) removing, from a reference material containing an extractant and a diluent, the diluent using a silica column; (b) generating a calibration curve by calculating each peak area of aliphatic hydroxy oxime and neodecanoic acid, which are extractants, by peak integration of gas chromatograms; and (c) calculating the peak area of the organic solvent used in DSX process through the steps (a) and (b) and comparing the peak area with the calibration curve of the step (b) to measure the concentration of aliphatic hydroxy oxime and neodecanoic acid.

A method for monitoring, evaluating and controlling a cyclic chromatographic purification process that involves at least two adsorbers. According to the method, one step is monitoring of the chromatogram, including the measurement of at least one current concentration-proportional signal in the liquid. Another step is conducting an evaluation of the chromatogram, including a comparison of at least one of the current concentration-proportional signals measured in the monitoring step with a threshold value thereof. A further step is controlling the chromatographic purification process by adapting the termination of the currently running phase as a function of the comparison of the evaluation step and initiating the next phase. Finally, according to the method, the sequence of steps is carried out in given order at least twice.

A chromatogram data processing system having an impurity detector including a differential chromatogram creator, a purity curve creator and a determiner. The differential chromatogram creator calculates a differential coefficient of an absorbance spectrum with respect to wavelength at a local maximum or local minimum absorption wavelength of the target component, and creates a differential chromatogram which shows a temporal change of the differential coefficient. The purity curve creator creates a purity curve which shows a temporal change of the difference between the degree of similarity of a spectrum on the target peak to a reference spectrum and a threshold of the degree of similarity which is determined taking into account the influence of noise components. The differential chromatogram and the purity curve are displayed on a display unit in a superposed form on a wavelength chromatogram created by a wavelength chromatogram creator.

An analysis system includes a separation system that provides compounds to a sample cell of a spectrometric system. The system analyzes spectral information from the spectrometric system by optimizing retention windows for the compounds and identifies quantities of the compounds by comparing spectral information within and outside the respective retention windows.
