Patent number: 11112391Abstract: A degree of similarity in the peak pattern between a mass spectrum obtained for an unknown target substance in a sample and a mass spectrum of a known specific substance is calculated (S4). If the degree of similarity is within a range of 80-60% (“No” in S6), the ratio between the signal intensities at two mass-to-charge ratios characteristic of the specific substance is calculated and compared with a reference value (S7 and S8). If the intensity ratio exceeds the reference value, the target substance is likely to be the specific substance. Therefore, as in the case where the degree of similarity is equal to or higher than 80%, it is concluded that the specific substance is contained in the sample (S10).Type: GrantFiled: September 25, 2015Date of Patent: September 7, 2021Assignee: SHIMADZU CORPORATIONInventors: Kengo Maeda, Tomohiro Kawase, Yutaro Yamamura, Tomoomi Hoshi

Patent number: 10794880Abstract: Sequential identification numbers are automatically provided and undisplayed, constant, unique numbers are assigned to each event registered in an analysis condition setting table 100. Since correspondence information between the identification numbers and the unique numbers changes due to the reassignment of identification numbers when an event is deleted from the table, event identification numbers for each compound are changed by referring to the correspondence information on a compound information table. As a result, it is possible to avoid the misalignment of event identification numbers between both tables. In addition, when an instruction is given to coordinate the time information or m/z information on both tables, the information on one table is reflected on the other table in accordance with the identification numbers.Type: GrantFiled: February 28, 2013Date of Patent: October 6, 2020Assignee: SHIMADZU CORPORATIONInventors: Yutaro Yamamura, Tohru Shiohama, Yuji Katsuyama

Patent number: 10090139Abstract: A mass analysis device capable of reliably detecting the peak in a mass chromatogram of a given m/z is equipped with a control unit, which generates a mass chromatogram and total ion chromatogram. The control unit includes a determination unit which, using the total ion chromatogram, determines the start time and end time of the peak in the total ion chromatogram by searching for the peak based on maximum value of detected intensity and searching for peak start time and end time based on slope of change of detected intensity; and a detection unit, which detects the peak in the mass chromatogram by making the start time and end time of the peak in the mass chromatogram the same as the start time and end time of the peak in the total ion chromatogram.Type: GrantFiled: October 15, 2014Date of Patent: October 2, 2018Assignee: SHIMADZU CORPORATIONInventor: Yutaro Yamamura
