摘要： An analytical data analysis system (2) is a system that identifies composition substances contained in the sample to be analyzed and non-composition substances that are not the composition substance contained in the sample to be analyzed by comparing a standard chromatogram and an analysis target chromatogram. The analytical data analysis system (2) includes a non-composition substance information holding part (12) holding identification information and information on a peak expression position on a chromatogram of substances that may exist as the non-composition substance, a chromatogram synthesis part (16) configured to synthesize the information held in the non-composition substance information holding part with the standard chromatogram in order to describe identification information and the peak expression position of the substances that may exist as the non-composition substance on the standard chromatogram in which the composition substances of the standard sample are described, and a chromatogram display part (18) configured to display the analysis target chromatogram together with the standard chromatogram synthesized by the chromatogram synthesis part (16) on the display device (6).

摘要： A program for assisting in determining a combination of parameter values of analysis conditions suitable for an intended analysis, makes a computer operate as: a graph-displaying section which displays, on a screen, a graph created based on data collected with a chromatograph device, to show a relationship between the parameter values and an analysis result obtained with the chromatograph device or a result of analytical processing based on the analysis result; an input-receiving section which receives a user's input of a constraint condition which specifies the upper/lower limit or range of a numerical value representing the analysis result or analytical-processing result; a search-conducting section which conducts a search for a combination of the parameter values which yields the analysis result or analytical-processing result in which the numerical value satisfies a predetermined search condition under the constraint condition; and a search-result-displaying section which displays a search result on the graph.

摘要： Roll-to-roll freeze-drying (lyophilization) system and process for facilitating freeze-drying processes and enabling the collection of data by which a freeze-drying process can be monitored and evaluated. Such a system includes a roll-to-roll freeze-drying apparatus adapted to continuously freeze and dry a liquid to form a freeze-dried and encapsulate freeze-dried sheet portions of the freeze-dried sheet to create premeasured pouches containing the freeze-dried sheet portions. The system further includes a metrology section that monitors any of the freeze-dried sheet and the freeze-dried sheet portions during the freezing and drying of the liquid to generate data for controlling the freezing and drying of the liquid.

摘要： Techniques for real-time or substantially real-time peak detection are described. In one embodiment, for example, logic coupled to memory may be configured to receive data from at least one analytical instrument and perform processing or analysis on the received data. Moreover, the logic may be configured to determine, via one or more GPUs or CPUs (or both), one or more peaks based on the processing or the analysis of the received data and generate peak detection data based on the detected one or more peaks in real-time or substantially real-time. Other embodiments are described.

摘要： A methodology scales supercritical fluid chromatography (SFC) and/or carbon dioxide based chromatography methods between different system and/or column configurations. The methodology includes measuring an average mobile phase density during a first separation utilizing C02 as a mobile phase component and substantially duplicating the average density profile for a second separation. Substantial duplication of the average mobile phase density (e.g., within about 10%, 5%, 2.5%, 1%, 0.5%, 0.1 %, 0.05%) results in chromatography for both system and/or column configurations having similar selectivity and retention factors. Average mobile phase density may be, either measured directly, calculated, or approximated using average pressure or density measurements. The average pressure profile may be used as a close approximation to duplicate average density profiles between separations.

摘要： A method for simultaneous determination of nitrogen and oxygen isotope compositions of natural nitrate and nitrite, which quantitatively converts natural nitrate and nitrite into an organic ester and a nitro-compounds respectively, and then nitrate and nitrite δ18O and δ15N are simultaneously determined by adopting a gas chromatography/pyrolysis/gas chromatography/isotope ratio mass spectrometry coupling technology (GC/Py/GC/IRMS). According to the method for simultaneously determining the nitrogen and oxygen isotope compositions of the natural nitrate salt and nitrite salt, the small amount of sample does not result in the loss, acquisition, exchange and fractionation of nitrogen and oxygen.
