| 摘 要： | 针对自制垂直引入式飞行时间质谱仪（orthogonal extraction time-of-flight mass spectrometer, O-TOFMS）的需要，运用直接数字频率合成 (direct digital frequency synthesis，DDS)技术，研制了射频四极杆的高压射频驱动电路装置。该驱动器频率可调范围为0.5~2 MHz，幅度最高达到1 000 Vp-p。该射频四极杆驱动器（radio frequency quadrupole driver，RFQ Driver）可用于分子离子反应器（molecule ion reactor，MIR）和RFQ驱动，其结构简洁、成本低、性能稳定可靠。

| Abstract: | The direct digital frequency synthesis (DDS) technique was applied to mass spectrometry domain. A radio frequency quadrupole driver (RFQ Driver) was designed and constructed for a high resolution orthogonal-extraction time-of-flight mass spectrometer (O-TOF MS). The frequency can be set from 500 kHz to 2 MHz at 1 Hz per step， and the magnitude is also tunable 0-1 000 Vp-p. The device is reliable, inexpensive and user friendly. |
