Abstract: Nonuse-indication information can be set for each peak on a mass spectrum collected in a compound database, as attribute information, the nonuse-indication information allowing the selection of whether to be used in a database search. For example, nonuse-indication information is set in advance to a noise peak mixed in actual measurement, an impurity-originated peak, and the like. In identifying a compound, when nonuse-indication information is read from the database for a database search together with a mass spectrum, an unnecessary information deleting section transmits a mass spectrum from which a peak set with the nonuse-indication information is deleted, to a compound candidate extracting section and a scoring section. Therefore, a peak set with the nonuse-indication information is ignored in, for example, calculating the score of a compound candidate, which allows a score with a high accuracy to be calculated, resulting in an improved identification accuracy.

Abstract: A mass spectrometry data processing apparatus having a function of displaying a plurality of MSn spectra in an arranged manner is allowed to display these MSn spectra in a state where a user can easily grasp presence or absence of a common neutral loss. A mass spectrometry data processing apparatus 20 that displays, on a display screen, an MSn spectrum resulting from mass spectrometric analysis of n?1 stage dissociation, where n is integer of two or more, of an ion, includes: a precursor ion identifying section 32 configured to identify, for each of a plurality of MSn spectra, a mass-to-charge ratios m/z of a precursor ion from which the MSn spectra are obtained; and a spectrum aligning section 33 configure to display the MSn spectra on the display screen in a vertically arranged manner such that positions of the mass-to-charge ratios m/z of the respective precursor ions are located at a same horizontal position of the display screen.

Abstract: A log analysis system includes a first processor unit, a second processor unit, a third processor unit, and a fourth processor unit. The first processor unit normalizes the detection log acquired by an acquirer, allocating the detection log into predefined monitoring target units, and outputs the monitoring target units. The second processor unit appends common information based on a predefined rule to each of the monitoring target units of the detection log output from the first processor unit, arranges the monitoring target units into information granularities based on the content of the detection log and common information, and outputs the monitoring target units as analysis unit information. The third processor unit gathers the analysis unit information output from the second processor unit and setting detection target event candidates based on a predefined rule, and outputs the detection target event candidates and the determination results.

Abstract: If multiple polyvalent ion peak candidates with different valences surmised to be derived from the target compound have been obtained, a mass chromatogram in the vicinity of the retention time of the target compound at the mass-charge ratio m/z of each polyvalent ion peak candidate is generated, and these are overlaid and displayed on the display screen. If the polyvalent ions are derived from the same compound, peaks of similar shape having a peak top near the retention time should appear in multiple mass chromatograms. Therefore, the user can check the displayed mass chromatograms and easily determine whether they reflect a combination of polyvalent ions derived from the target compound (a) or not (b).

Abstract: In a liquid chromatograph mass spectrometer (LC/MS), three kinds of graphic data (or graphs) composed of an LC chromatogram, an MS chromatogram, and an MS spectrum should be mutually compared to perform a specific analysis. Conventionally, a plurality of graphs are arranged for comparison on one monitor in accordance with a user's purpose. However, when an operation is once terminated and then the graphs are displayed again or in other processes, their display formats are not reproduced. Hence, the user needs to manually set the desired layout every time, which is cumbersome. The data analysis system according to the present invention has been developed to solve this problem. The data analysis system has a layout memory for storing layout information including a plurality of kinds of graphs to be displayed on the monitor and the display position of each graph, and refers to the layout information when displaying the graphs.

Abstract: To form predetermined patterns on flexible substrates made of an inorganic material, in the case where one of substrates in pair is subjected to a processing operation that causes swelling or shrinkage of the substrate, the other substrate is also subjected to the processing operation irrespective of whether or not the other substrate requires the processing operation.

Abstract: With DC constant current applied to an end of one of transparent electrodes by a constant current application terminal, a voltage is measured at an end of a transparent electrode adjacent to the foregoing electrode by a voltage detection terminal, while a common electrode is earthed by applying a brush earth terminal thereto in the vicinity of the foregoing transparent electrode. If the transparent electrode is broken, the DC constant current application circuit detects a voltage saturation state, whereas if the transparent electrode is short-circuited, the DC voltage detection circuit detects variation in the foregoing voltage. A short-circuiting/wire breakage memory circuit stores the detected irregularity of the voltage as defect information, and either wire breakage or short-circuiting is detected on the basis of the defect information.
