The degree of ion dissociation which occurs within a first intermediate vacuum chamber (212) maintained at a comparatively low degree of vacuum depends not only on the amount of energy of the ion but also on the size and other properties of the ion. Accordingly, a predetermined optimum level of DC bias voltage is applied to an ion guide (24) so as to create, within the first intermediate vacuum chamber (212), a DC electric field which barely induces the dissociation of an ion originating from a target compound in a sample while promoting the dissociation of an ion originating from a foreign substance which will form a noise signal in the observation of the target compound. The optimum DC bias voltage is previously determined by creating extracted ion chromatograms based on data collected under various DC bias voltages and evaluating the SN ratio using the chromatograms. Consequently, the accuracy and sensitivity of the quantitative determination is improved as compared to a conventional system in which only the signal strength of the target compound is considered.

According to the structure of the present invention, the structure is improved as the mobile radiation device can be assuredly stopped on the horizontal pathway without jounce. Specifically, the present invention provides the idea in the case of moving on the slope pathway Specifically, the braking control element 18 turns the brake module 19 operative when the velocity of the wheeled platform increases despite beginning of braking the wheeled platform 1 by the velocity lowering control element 17. In such cases, according to the present invention, despite beginning of braking the wheeled platform 1 by the velocity lowering control element 17, when the velocity of the wheeled platform 1 increases, the brake module 19 is turned operative promptly so that the incident in that the wheeled platform 1 continues to move for a long time ignoring the direction to stop the wheeled platform 1 moving on the slope can be controlled.

A cloud of ions captured in an ion trap (2) is irradiated with a stream of hydrogen radicals cast through a radical particle introduction hole (26) bored in a ring electrode (21) at a flow rate of 410^(10) [atoms/s]. As a result, a radical induced dissociation which does not rely on the transfer or capture of electrons occurs within the ion trap (2), whereby c/z-type fragment ions are efficiently generated. After the irradiation with the hydrogen radicals, a supplemental collision-induced dissociation process may performed by introducing inert gas into the ion trap (2) and resonantly exciting the ions, in order to further promote the generation of the c/z-type fragment ions. In this manner, according to the present invention, it is possible to achieve radical induced dissociation of singly-charged ions derived from a peptide and use the thereby generated c/z-type fragment ions for mass spectrometry.

A method of controlling a DC power supply to change a DC offset voltage applied to a component for manipulating charged particles. The method includes, whilst an AC voltage waveform is being applied to the component: controlling the DC power supply to produce an initial DC offset voltage that is applied to the component via a link that causes the DC offset voltage at the component to lag behind the DC offset voltage produced by the DC power supply when the DC offset voltage produced by the DC power supply is changed; then controlling the DC power supply to produce an overdrive DC offset voltage that is applied to the component via the link for a predetermined period of time; then controlling the DC power supply to produce a target DC offset voltage that is applied to the component via the link, wherein the target DC offset voltage is between the initial DC offset voltage and the overdrive DC offset voltage.

According to the image processing device of the present invention, the binarization image having increasing assuredness can be generated by extracting the metal piece from the original image with the graph cut processing. The image processing device of the present invention is the system that executes an image trimming from near the center of the intermediate region after the metal piece is divided relative to the image of the roughly extracted binarization image near the center of the intermediate region in that it is difficult to decide whether it belongs to the metal piece or not. Following such steps, the intermediate region can be assuredly trimmed while executing the image trimming in the region as small as possible.

An excessive overshoot preventing unit (16) is connected to a loop in which a command voltage Vf according to a difference between: a voltage obtained by dividing an output voltage Vout as a high voltage; and a control voltage Vcont set from the outside is obtained and fed back to each of drive circuits (3 and 5) of a positive voltage generating unit (2) and a negative voltage generating unit (4). The excessive overshoot preventing unit (16) clamps the command voltage Vf at a voltage value according to the control voltage Vcont. An overshoot that occurs in the voltage generating unit (2 or 4) at the time of polarity switching mainly depends on a circuit constant, and hence the amount of overshoot is excessive in the case of a low-voltage output even if the amount of overshoot is optimal in the case of a rated output. To deal with this, in this power unit, the overshoot of the command voltage Vf is suppressed by the excessive overshoot preventing unit (16), and hence the output voltage can be promptly settled to a target voltage even in the case of a low-voltage output.
