    摘要: An numerical analysis time which is assigned to mass select one ion species having a specific mass-to-charge ratio mass selected is divided into the first part time and the second part time, and a dipole auxiliary electric field capable of spatially reducing a spread is superimposed in the first part time of the numerical analysis time and a quadrupole auxiliary voltage capable of rapidly emitting ions when position coordinates are large is superimposed in the second part of the time. Therefore, the initial spatial spread is reduced in the first part time and the trajectories of ions is rapidly amplified in the second part time, and the ions are emitted. Thus, the entire mass sweep time can be reduced and a high-resolution numerical analysis can be accelerated.

    摘要: A sample separated through a pre-processor part having a gas chromatography (GC) or a liquid chromatography (LC) and a moving bed eliminating part is ionized by an ion source and mass-analyzed by a mass-analyzing part. The mass-analyzed ions are deflected and focused by a deflecting portion and a focusing portion in a deflecting and focusing part, and is detected by an ion detecting part. The result of detection is processed by a data processing part.

    摘要: A tubular insert with a small internal volume is disposed inside the vaporization chamber at the inlet of a capillary column of a gas chromatograph such that the sample with a solvent injected into the vaporization chamber is carried by a carrier gas through the insert into the column. The internal volume of the insert is such that the retention time of the carrier gas through the insert is less than 4 seconds. A heater is controlled to maintain the temperature inside the vaporization chamber within a specified range above the boiling point of the solvent as the sample is injected into the vaporization chamber, and this temperature is subsequently raised to a final temperature above the boiling points of the components to be analyzed. The carrier gas pressure is temporarily increased for better efficiency as the sample is injected.

    摘要: In a mass analyzer, an acceleration voltage is applied to an ionization chamber in which a voltage to be applied to repeller electrodes to repel ions is generated with reference to the acceleration voltage and a repeller voltage source is linked with a controller by use of a photocoupler or the like such that the repeller voltage is adjusted with the repeller voltage source electrically insulated from the controller. The repeller voltage can be easily and automatically adjusted by use of a low-voltage control signal so as to obtain a sensitivity developing the maximum value of the quantity of detected ions and hence a qualitative or quantitative analysis of a sample can be achieved with a high sensitivity. The controller processes digital signals and appropriate parameters are stored in a memory. Each parameter is changed with the center of change set to an appropriate parameter previously used and consequently the automatic control is simplified.

    摘要: In order to suppress freezing of a water content within a breather tube, a heater (13) is arranged within a breather tube (11) joining a cylinder head cover (10) and an air cleaner (8). A main body of the breather tube (11) is constituted by a joint tube (18) arranged in a middle, and partial tubes (22, 23) connected to both ends thereof. The heater (13) has a heating element (14) corresponding to a heating element, and has a heater case (21) accommodating the heating element (14) in a state of being pinched by electrodes (15), and is arranged in a center portion of the joint 18. A slot (18a) for inserting the heater (13) is formed in the joint tube 18. A heat radiating body (20) extended along the breather tube (11) is joined to the heater case (21). An outer peripheral portion of the breather tube (11) is covered by an insulative outer tube (24).
