  • Publication number: 20210066057
    Abstract: An analytical device, includes: an ionization unit that ionizes carrier gas introduced into the separation column; a mass separation unit that mass-separates ions generated in the ionization unit; a detection unit that detects the ions mass-separated by the mass separation unit in amplification with a predetermined multiplication factor, and outputs a detection signal; an analysis unit that analyzes the detection signal having been output from the detection unit; and an adjustment unit performs an adjustment of the multiplication factor of the detection unit and/or voltage applied to an electrode of an ion transport system of the mass separation unit based on magnitude of the detection signal corresponding to the carrier gas detected by the detection unit.

  • Publication number: 20200126780
    Abstract: 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.

  • Patent number: 10488376
    Abstract: 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.

  • Patent number: 10329825
    Abstract: A window regulator includes a carrier plate holding a windowpane, a drum rotated by driving a motor that generates a driving force, a wire whose one end is connected to the carrier plate and whose other end is connected to the drum, a wire end fixed to an end on a side of the one end of the wire, and a housing member that is formed of a synthetic resin and houses the wire end. The housing member is configured to define a housing hole that is surrounded by a base in which an inserting hole to insert the wire is formed, and a sidewall that is formed extending from an outer edge of the base. The wire end is housed in the housing hole while being pressed against a protrusion that protrudes from the sidewall.

  • Patent number: 10262848
    Abstract: 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.

  • Patent number: 9347919
    Abstract: The present invention provides a method and apparatus for rapidly extracting the analyte existing in the liquid phase in analyzing an analyte “having a large partition coefficient in gas-liquid equilibrium”, “having a high water solubility”, or “having a low olfactory threshold” by a gas-liquid contact extraction method, and further provides, a method and apparatus for unmanned continuous sample introduction of the analyte to a GC or the like for a long time. In the present invention, using a gas-liquid contact extractor to which a sample liquid is continuously introduced from above and a purge gas from beneath, the analyte in the sample liquid is extracted by gas-liquid contact between the sample liquid and the purge gas. A discharge pipe is connected to the bottom of the gas-liquid contact extractor, the pipe having a liquid sump through which the sample liquid is discharged, while blocking the outflow of the purge gas from the liquid sump.

  • Patent number: 9312115
    Abstract: Flanges (10a) of an attachment plate (10) integrally combined with an ion detector (5) are fixed to an inner surface of a vacuum chamber (1) via cushioning members (12), such as O-rings. Although the vacuum chamber (1) mechanically vibrates due to a turbomolecular pump attached to it, this vibration is absorbed by the cushioning members (12), whereby the vibration of the ion detector (5) is suppressed. As a result, the noise which occurs with a vibration of the ion detector (5) and is superposed on the detection signal is reduced. Thus, the quality of the detection signal can be improved by a simple and inexpensive structure.

  • Patent number: 8806965
    Abstract: A headspace sample introduction device which collects a sample gas from a sample container and introduces the gas into a predetermined analyzer is provided. The device includes a sample tray 10 capable of holding at least one sample container 100 storing a liquid sample or a solid sample, a heating means 30 for heating at least one sample container 100 taken from the sample tray 10, a sample-gas collecting means 40 for collecting a sample gas from the upper space in the sample container 100 held in the heating means 30, and a cooling transfer means 20 for keeping and cooling at least one sample container 100 taken from the heating means 30 and returning the cooled sample container 100 to the sample tray 20. Since the headspace sample introduction device can return the heated sample containers 100 to the sample tray 10 after they are cooled with the cooling transfer means 20, the hot sample containers can be assuredly prevented from contacting the user.

  • Patent number: 8803086
    Abstract: Elements are arranged so that a straight ion-beam axis extending from an ion source through a first ion lens and a front-stage quadrupole mass filter and a straight ion-beam axis extending through the ion guide in a collision cell and a rear-stage quadrupole mass filter obliquely intersect with each other at a predetermined angle in a space between the front-stage quadrupole mass filter and the collision cell. Metastable helium molecules generated in the ion source may pass through the front-stage quadrupole mass filter but will be removed before reaching the exit of the collision cell. On the other hand, precursor ions which have passed through the front-stage quadrupole mass filter are made to bend along an inflected ion-beam axis under the influence of a direct-current electric field created by an entrance ion lens, to be efficiently introduced into the collision cell.
