Patent number: 11043371Abstract: Four rod electrodes (50a to 50d) for separating ions according to a mass-to-charge ratio are held by two rod holders (51). The rod holders (51) are attached to metal holder sustaining stands (52) provided on a bottom surface of a vacuum housing (1). A coating film layer (10) is formed by a black nickel plating process on parts of wall surfaces in the vacuum housing (1), an inlet lens (4), and an outlet lens (6), the parts facing a quadrupole mass filter unit (5). The emissivity of the coating film layer (10) is higher than that of Al or the like, and thus radiant heat from the quadrupole mass filter unit (5) is efficiently absorbed by the coating film layer (10). Therefore, heat generated in the rod holders (51) due to dielectric loss is efficiently dissipated, and deformation of the rod holders can be reduced.Type: GrantFiled: February 7, 2018Date of Patent: June 22, 2021Assignee: SHIMADZU CORPORATIONInventors: Manabu Ueda, Kota Nagasao

Publication number: 20210175066Abstract: Four rod electrodes (50a to 50d) for separating ions according to a mass-to-charge ratio are held by a rod holder (51). The rod holder (51) is placed on a metal holder sustaining stand (52) provided on a bottom surface of a vacuum housing (1), and is fixed while being pressed by a fixation band (53) fixed to the holder sustaining stand (52) with screws (56). The fixation band (53) is made from phosphor bronze having higher thermal conductivity than thermal conductivity of stainless steel or the like. Therefore, heat generated in the rod holder (51) due to dielectric loss is not only directly transmitted to the holder sustaining stand (52), but also efficiently transmitted to the holder sustaining stand (52) through the fixation band (53). With this, the heat of the rod holder (51) is efficiently dissipated, and non-uniformity of temperature of the rod holder can be reduced.Type: ApplicationFiled: February 7, 2018Publication date: June 10, 2021Applicant: SHIMADZU CORPORATIONInventors: Manabu UEDA, Kota NAGASAO

Publication number: 20210151313Abstract: A vacuum chamber 11 for forming a vacuum space has two side walls opposite to each other across an ion beam axis extending within the vacuum space. One of those side walls is openable and closeable. An ion optical element 21 is placed on a base 33, which is located on the bottom surface of the vacuum chamber. A fixation band 213 fixes the ion optical element on the base by holding the element between the base and the fixation band so as to press the element onto the base. A band-catching portion 10d, located on an inside face of a side wall of the vacuum chamber on the opposite side from the openable-and-closeable side wall, catches one end of the fixation band. A band-fixing portion 214, located on the base on the side where the openable-and-closeable side wall is present, fixes the other end of the fixation band to the base.Type: ApplicationFiled: September 16, 2020Publication date: May 20, 2021Applicant: SHIMADZU CORPORATIONInventors: Manabu UEDA, Takashi UMEMOTO

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

Patent number: 9761432Abstract: A dwell time calculation table (51a) showing a correspondence relation between a CID gas pressure inside a collision cell (31) and a dwell time for data collection is stored in a processing condition parameter memory (51) of a controller (50). In the table (51a), as the CID gas pressure becomes higher, the dwell time becomes longer. When an instruction to execute an MRM measurement mode is given, the controller (50) determines the dwell time in accordance with the currently set CID gas pressure, and controls a data collector (41) to accumulate detection signals from an ion detector (34) during the determined dwell time and obtain the accumulated value. If the CID gas pressure inside the collision cell (31) is high, a decrease in ion speed becomes remarkable, and the rising of the ion intensity becomes slow. However, if the dwell time becomes long, influences of the slow rising on the accumulated value are relatively reduced, and the accuracy of the accumulated value is enhanced.Type: GrantFiled: May 21, 2015Date of Patent: September 12, 2017Assignee: SHIMADZU CORPORATIONInventor: Manabu Ueda
