  • Patent number: 10254258
    Abstract: A two-dimensional chromatogram creator creates a two-dimensional chromatogram based on data collected by a comprehensive two-dimensional GC/MS analysis. An extraction condition conformity determiner determines whether or not each MS/MS spectrum obtained through the analysis conforms to a compound extraction condition previously stored in a storage section, such as the presence of a specific peak on the MS/MS spectrum. Each spectrum which conforms to the condition is extracted. This spectrum is most likely to reflect a partial structure of a compound in which an analysis operator is interested. Accordingly, a condition conformity information superposing displayer displays a marker whose appearance varies according to the compound extraction condition, at a position corresponding to the retention time of the extracted spectrum on the two-dimensional chromatogram.

  • Patent number: 10249480
    Abstract: Peak information is collected from an MS/MS spectrum in which the product ions generated from ions originating from a plurality of compounds are mixed. Using one of the m/z values of a plurality of ion species as precursor-ion information and the peak information of the MS/MS spectrum as product-ion information, a database search is performed to find candidate compounds for each compound, and a standard MS/MS spectrum of each candidate compound is obtained. For each combination of the candidate compounds, a virtual MS/MS spectrum is created by integrating the standard MS/MS spectra of those candidate compounds, and the degree of similarity between the virtual MS/MS spectrum and the measured MS/MS spectrum is calculated. If the candidate compounds are correct compounds, the degree of similarity will be high. Accordingly, the compound names and other results are visually presented to users in descending order of the degree of similarity.

  • Publication number: 20180358215
    Abstract: A columnar rod reference member made of a material whose coefficient of thermal expansion is different from a flight tube is placed in contact with the tube. One end of the tube and o the reference member are fixed to each other with a fixture part. A distance measurement sensor measures the difference in length between the tube and the reference member whose lengths fluctuate due to a change in temperature. A displacement of the difference in length, as expressed by a proportion, is larger than that of the length of the flight tube. The difference in length is far smaller than the length of the flight tube. This improves detection of the displacement due to thermal expansion with a strain gauge or sensor. The m/z values in mass spectrum data are corrected based on the measured values of the displacement, whereby a highly accurate mass discrepancy correction is achieved.

  • Publication number: 20180218892
    Abstract: For every acquisition of a set of mass spectrum data, a mass calibrator (determines the amount of mass discrepancy using the appearance position of a peak originating from an internal standard substance having a known m/z value, and performs a process for correcting the mass discrepancy. A mass calibration information collector (collects the amount of mass discrepancy or mass correction quantity for each set of mass spectrum data. After the completion of the measurement, a three-dimensional display information creator creates a three-dimensional graph showing the large number of collected mass correction quantities plotted in a three-dimensional space in which the retention time in a primary column and the retention time in a secondary column in a comprehensive two-dimensional LC unit are represented by two mutually orthogonal axes while the mass correction quantity is represented by the axis orthogonal to those two axes.

  • Publication number: 20180197726
    Abstract: An analysis operator checks an optical microscopic image obtained with an imaging mass microscope and indicates a color characteristic of an area which the analysis operator is focusing on. An optical microscopic image feature extractor calculates luminance distribution data in the indicated color. An image position adjustment processor performs a position adjustment process on a luminance distribution image derived from the optical microscopic image and an MS imaging graphic, while a resolution adjuster equalizes their spatial resolutions. A statistical analysis processor calculates a coefficient of spatial correlation between the luminance distribution image and the MS imaging graphic for each mass-to-charge ratio. Based on the calculated correlation coefficients, an analysis result display processor extracts a mass-to-charge ratio which shows an ion intensity distribution similar to the luminance distribution image. and displays it on a display unit.

  • Patent number: 10020173
    Abstract: A chromatograph mass analysis data processing method for obtaining pertinent information 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. When the operator specifies a desired range, the data contained in the range specified are collected, the signal intensities along the mass-to-charge ratio axis direction are summed up for every retention time to create a summed mass chromatogram based on the summed value. Simultaneously, the signal intensities along the retention time axis direction are summed up for every mass-to-charge ratio to create a summed mass spectrum based on the summed value. These are then displayed on the same screen of the isointensity line graph.

  • Patent number: 9897580
    Abstract: 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.
