Patent number: 11486866Abstract: 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.Type: GrantFiled: November 9, 2017Date of Patent: November 1, 2022Assignee: SHIMADZU CORPORATIONInventors: Takeshi Osoekawa, Yusuke Hida, Yuzi Kanazawa, Shinji Kanazawa, Yohei Yamada, Hiroyuki Yasuda, Akihiro Kunisawa

Patent number: 11302039Abstract: 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.Type: GrantFiled: November 9, 2017Date of Patent: April 12, 2022Assignee: SHIMADZU CORPORATIONInventors: Takeshi Osoekawa, Yusuke Hida, Yuzi Kanazawa, Shinji Kanazawa, Yohei Yamada, Hiroyuki Yasuda, Akihiro Kunisawa, Hidetoshi Terada
