Patent number: 11264230Abstract: Measurement of a standard sample is repeated under control of an analysis control unit (94) while a CD voltage applied to a conversion dynode (61) of a detection unit (6) is gradually changed by a CD voltage adjustment unit (96). Then, every time a measured mass spectrum is obtained, a spectrum pattern determination unit (93) determines whether a pattern of the measured mass spectrum matches a pattern of a standard mass spectrum of a standard sample in a compound database (92), and determines the CD voltage at the time of being regarded as matching to be the set value. When the pattern of the mass spectrum is adjusted by changing the voltage applied to the ion lens (3), performance such as sensitivity is likely to be unstable due to stain on the lens electrode or the like, but since the detection unit (6) is unlikely to be affected by such a stain, unstable performance can be avoided.Type: GrantFiled: June 29, 2017Date of Patent: March 1, 2022Assignee: SHIMADZU CORPORATIONInventor: Manabu Shimomura

Patent number: 10488376Abstract: In a chromatogram mass spectrometer's data processing system, if the intensity of a target peak originating from a target component at a target mass-to-charge ratio is equal to or higher than a threshold, the mass-to-charge ratio of a peak having a signal intensity lower than the threshold on the mass spectrum corresponding to the point in time where the target peak appears is designated as a correction mass-to-charge ratio. A mass spectrum at a point in time in the target peak where the signal intensity does not exceed the threshold is acquired. A sensitivity factor is calculated by dividing the strength at the target mass to-charge ratio on this mass spectrum by the strength at the correction mass to-charge ratio on the same spectrum. A mass chromatogram at the correction mass-to-charge ratio is created. This mass chromatogram is multiplied by the sensitivity factor to create a corrected mass chromatogram.Type: GrantFiled: March 3, 2014Date of Patent: November 26, 2019Assignee: SHIMADZU CORPORATIONInventors: Manabu Shimomura, Kaori Tanaka

Patent number: 10262848Abstract: In a device adjustment process, when a solenoid valve is opened, a gas resulting from vaporization of PFTBA held in a container is drawn into an ion source, a relationship between ambient temperature and a correction coefficient for actual signal values is experimentally determined beforehand. In an actual adjustment process, an ambient temperature acquirer reads the ambient temperature and refers to the correction information to determine the correction coefficient corresponding to the ambient temperature at that moment. A signal value corrector multiplies an actually measured peak area value by the correction coefficient to correct the actual signal value. A device adjustment controller adjusts a voltage applied to an ion detector so that the corrected actual signal value matches with a reference signal value. The voltage applied to the ion detector can be thereby adjusted so that the detector has the same level of gain independent of the ambient temperature.Type: GrantFiled: January 21, 2015Date of Patent: April 16, 2019Assignee: SHIMADZU CORPORATIONInventor: Manabu Shimomura
