    摘要: In a scan measurement in which a mass scan is repeated across a predetermined mass range, when a voltage is returned from a termination voltage of one scan to an initiation voltage for the next scan, an undershoot or other drawbacks occur to destabilize the voltage value. Therefore, an appropriate waiting time is required. Conventionally, this waiting time has been set to be constant regardless of the analysis conditions. On the other hand, in the quadrupole mass spectrometer according to the present invention, the mass difference ΔM between the scan termination mass and the scan initiation mass is computed based on the specified mass range, and a different settling time is set in accordance with this mass difference. When the mass difference ΔM is small and hence requires only a short voltage stabilization time, a relatively short settling time is set. This shortens the cycle period of the mass scan, which increases the temporal resolution.

    摘要: A laser marking system of the present invention is provided with an irradiation position changing device on a laser beam path for changing the irradiation positions of the laser beam corresponding to each marking area when a marking area including a plurality of irradiation marking areas is formed by irradiating the workpiece with the pulse laser beam which has passed a pattern of a mask. The plurality of irradiation marking areas are successively irradiated with the pulse laser beam from an irradiation position to form a marking area. Since the marking area larger than each irradiation marking area can be obtained, the whole laser marking system can be made smaller in size without increasing the output power of the pulse laser generator.
