  • Publication number: 20200292509
    Abstract: When chromatogram data for a target sample have been acquired, a peak position estimator determines an estimated result of the position of the starting and/or ending point of a peak as well as the confidence value representing the reliability of the estimation, using a trained model stored in the trained model storage section. Normally, a plurality of estimated results of the starting point and/or ending point of the peak are acquired for one peak. A peak information correction processor identifies a candidate having the highest confidence as a prime candidate, and superposes a plurality of candidates including the prime candidate, with their respective confidence values, on a displayed chromatogram. An operator referring to the confidence values selects a peak which needs close checking or correction, and corrects the starting point and/or ending point of the selected peak, for example, by selecting and indicating a candidate other than the prime candidate.

  • Publication number: 20200279408
    Abstract: A model constructed by a training process using the technique of deep learning using the training data including images created from a large number of chromatograms and correct peak information is previously stored in a trained model storage section. When chromatogram data for a target sample acquired with an LC measurement unit are inputted, an image creator converts the chromatogram into an image and creates an input image in which one of the two areas divided by the chromatogram curve as the boundary in the image is filled. A peak position estimator inputs the pixel values of the input image into a trained model using a neural network, and obtains the position information of the starting point and/or ending point of the peak and a peak detection confidence as the output. A peak determiner determines the starting point and/or ending point of each peak based on the peak detection confidence.

  • Patent number: 10416136
    Abstract: A controlling apparatus 110 to control an operation of an analyzing apparatus 1 and make the analyzing apparatus 1 execute a predetermined analysis, the controlling apparatus 110 including: a communicating module 60 that maintains reception of electricity when the analyzing apparatus 1 is in a power-on state, and is capable of receiving a control signal from an external apparatus 2 at all times; and a unit power controlling section 23 for acquiring the control signal through the communicating module 60, stopping electricity supply to a unit 31, 321, 322, 323 and/or 324 of the analyzing apparatus 1 at a first timing based on the control signal, and restarting the electricity supply to the unit 31, 321, 322, 323 and/or 324 at a second timing based on the control signal, so as to effectively suppress the electricity consumption when the analysis is not executed and facilitate the restart of the analysis.

  • Publication number: 20190129917
    Abstract: A first reference line that is a regression line obtained from data within a predetermined range including a starting point of a peak detected from data of a graph showing changes in intensity with respect to a parameter, a second reference line that is a regression line obtained from data within a predetermined range including a ending point of the peak, and a third reference line connecting the starting and ending points, and one or more intermediate control points in a triangle defined by the first, second, and third reference lines are determined; and a Bezier curve between the starting point and the ending point is created to be determined to be a baseline of the peak, the Bezier curve being determined by control points of the starting point, the one or more intermediate control points, and the ending point in order on a parameter axis.

  • Publication number: 20190113486
    Abstract: A peak detecting method according to the present invention includes a first peak detecting step (S1) of detecting, with a first detection sensitivity, one or more peaks in object data whose peak is to be detected; and a second peak detecting step (S5) of detecting one or more peaks in the object data with a second detection sensitivity that is different from the first detection sensitivity. With this method, since two kinds of detection are performed at the different detection sensitivities, a shoulder peak (or a non-shoulder peak) candidate can be chosen from peaks that are detected with one of the detection sensitivities but are not detected with the other detection sensitivity, and thus, a shoulder peak can be appropriately detected with ease.

  • Publication number: 20190064130
    Abstract: A method for detecting a peak in data of a chromatogram or a spectrum, includes: detecting multiple tentative peaks in the data on the basis of a predetermined criterion; determining an actual measurement value of a predetermined feature value indicating a size of a tentative peak from each of the detected multiple tentative peaks, the feature value; determining a smoothed curve on the basis of respective horizontal axis values and actual measurement values of the multiple tentative peaks; determining a reference value of the feature value with respect to each of the multiple tentative peaks from the smoothed curve; and detecting, of the multiple tentative peaks, a tentative peak whose actual measurement value is within a predetermined range from the corresponding reference value as a true peak. Only tentative peaks whose actual measurement value is within a predetermined range from the corresponding reference value as a true peak.
