| 20090001261 | CHROMATOGRAPH MASS ANALYSIS DATA PROCESSING APPARATUS - A chromatograph mass analysis data processing apparatus is provided for obtaining pertinent information, with a simple operation, on a compound series including a plurality of compounds whose structures and characters are similar. Based on the data obtained by a chromatograph mass analysis, a two-dimensional isointensity line graph is created and displayed with a retention time and a mass-to-charge ratio on the two axes and with a signal intensity represented with a contour (S | 01-01-2009 |
| 20090008548 | CHROMATOGRAPH MASS SPECTROMETER - A chromatograph mass spectrometer is provided for obtaining the information pertinent to a structural analysis, with a simple operation, on a compound series including a plurality of compounds whose structures and characters are similar. First, based on the data obtained by a normal LC/MS analysis, a two-dimensional isointensity line graph is created and displayed with a retention time and a mass-to-charge ratio on the two axes and with a signal intensity represented in contour (S1 and S2). When the operator specifies a desired range by a drag operation or the like by a mouse (S3), peaks included in the range specified are extracted and based on the peaks, precursor ions are selected (S4 through S6). Then a schedule is created so that an MS | 01-08-2009 |
| 20090020693 | CHROMATOGRAPH MASS ANALYSIS DATA PROCESSING APPARATUS - The invention provides a chromatograph mass analysis data processing apparatus in which operators can easily obtain information about plural compounds that characterize a difference between plural samples on the basis of the result of a multivariate analysis. A set of data collected by LC/MS analyses of plural samples is subjected to a multivariate analysis (principal component analysis) to create and display a loadings plot. On this loadings plot, the operator can specify a range A to select one or more characteristic data points that seem influential in the grouping of the plural samples. In response to this operation, one or more markings B indicating the peaks corresponding to the data points selected within the range A are displayed on an isointensity line graph whose two axes indicate the retention time and mass-to-charge ratio. These markings enable the operator to check, for example, that the compounds that are influential in the grouping of the samples belong to a specific compound series. | 01-22-2009 |
| 20090189073 | MASS SPECTROMETRY SYSTEM - A mass spectrometry system, in which a sample is introduced into each of a triple quadrupole-type mass spectrometry apparatus and another mass spectrometry apparatus, approximately concurrently in a parallel manner. The triple quadrupole-type mass spectrometry apparatus is operable to perform a neutral loss scan, and, when a specific ion is detected, a data processing section is operable to instruct a control section to initiate a mass spectrometric analysis in the other mass spectrometry apparatus. The control section is operable to control each device of the other mass spectrometry apparatus to allow the other mass spectrometry apparatus to perform a mass spectrometric analysis for the specific ion with a high degree of accuracy. A data integration processing section is operable to integrate respective analysis results obtained by data processing sections as if they are obtained from a single mass spectrometry apparatus. | 07-30-2009 |
| 20100044562 | MASS-ANALYZING METHOD AND MASS SPECTROMETER - Based on the mass spectrum obtained by mass-analyzing a sample, the composition of the unknown substance is deduced, and after that, an MS/MS analysis is performed in which the unknown substance is set to be a precursor ion. Then, based on the peaks appearing on the MS/MS spectrum, the actually measured mass of each product ion is obtained (S | 02-25-2010 |
