Patent number: 10935528Abstract: The detection of minute amounts of components that have been undetectable due to an influence of a mobile phase or reagents or the like added to the mobile phase is realized in LC-MS. At the outset, blank measurement is executed, and an m/z value MBG of a background signal derived from a mobile phase or the like is extracted on a mass spectrum obtained by the blank measurement (S2-S4). An analysis method is then created that executes scanning measurement in a plurality of divided m/z ranges in which the m/z value MBG of the background signal has been excluded from a predetermined m/z range. An LC/MS analysis of the target sample is executed according to the analysis method (S5-S6). When a total ion chromatogram (TIC) is created from data obtained by the LC/MS analysis, influence of the background signal hardly appears in the TIC, and the base line is lowered.Type: GrantFiled: June 28, 2016Date of Patent: March 2, 2021Assignee: SHIMADZU CORPORATIONInventors: Manabu Ueda, Jun Watanabe
