摘要： In an RBW filter, a bandwidth is set so as to selectively pass a frequency component of only a desired signal bandwidth of the measured signals that have been frequency converted into a normalized intermediate frequency signal. A waveform detector detects a signal that passes through the RBW filter. An A/D converter samples the signal detected by the waveform detector at a predetermined sampling rate at which a Nyquist frequency is within the frequency bandwidth of the RBW filter, thereby converting the sampled signal into digital data. A data storage section stores the digital data converted by the A/D converter. A signal processing section re-samples the digital data stored in the data storage section so as to reproduce a bandwidth of the detection signal of the waveform detector, thereby generating arbitrary time data. A display section displays the arbitrary time data generated by the signal processing section while time and amplitude are defined on horizontal and vertical directions on the display screen.

摘要： Provided is a technique of analyzing particles in real time while collecting and condensing the particles continuously. Gas and/or particles as a detection target substance that are attached to an authentication target 2 are removed by air flow from a blowing region 5. The removed sample is sucked and is condensed and sampled at a sampling region 10, and ions of the sample are generated at an ion source 21 and are then subjected to mass analysis at a mass analysis region 23. Determination of the obtained mass spectrum is made as to the presence or not of a mass spectrum derived from the detection target substance, and a monitor 27 displays a result thereof. Thereby, the detection target substance attached to the authentication target 2 can be detected continuously in real time, promptly and with a less error rate.

摘要： The quantitative accuracy of analysis is improved without reducing the dynamic range for measurement of concentrations by performing stable ionization through electrospray or the like which repeats sampling and ionization using a movable probe electrode.A voltage is applied from a high-voltage power source 4 to a sample transport electrode 7 having a plurality of probe electrodes 1 and a driving section 3 drives the sample transport electrode 7 to rotate. The plurality of probe electrodes 1, to which a sample solution 5 is adhered, are sequentially transported to an inlet 21 of a mass spectrometer 20, thus electrospray ionization is continuously performed.
