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 |

20140163902 | MASS ANALYSIS DATA ANALYZING METHOD AND APPARATUS - A method and apparatus for estimating the structure of an unidentified substance produced from an original substance having a known structural formula through partial structural change caused by metabolism or the like. A mass difference between a product ion, originating from the unidentified substance and having a partial structure including a structural change site, and a product ion, originating from the original substance and having a partial structure prior to the structural change, is equal to the mass difference between the original substance and the unidentified substance. Therefore, when pairs of product ions each having such a mass difference are selected to be compared with partial structures obtained from the known structural formula of the original substance, a minimum common partial structure having the structural change site is obtained. | 06-12-2014 |
20150034812 | MULTI-DIMENSIONAL CHROMATOGRAPH SYSTEM - In a two-dimensional LC system configured to introduce components trapped in a trap column during a fractionation period T into a second-dimension column, separate components, and then detect the components using a mass spectrometer, a data collection unit receives a signal which indicates timing to delimit the fractionation period T, determines the first data item in the fractionation period T, adds measurement start point identification information to the first data item, and stores all the data in a data storage unit. A two-dimensional chromatogram creation unit recognizes the first data item in each fractionation period T from the read data, and create a two-dimensional chromatogram by aligning data so that the first data items will be aligned at the top along an abscissa. | 02-05-2015 |
