CORONA DISCHARGING DEVICE AND ION MIGRATION SPECTROMETER HAVING SAME |
摘要 |
<p>A corona discharging device (50), including a first electrode (12), the first electrode (12) including a first inner cavity portion (530) of a roughly cylindrical shape and a second inner cavity portion (550) of a roughly conical shape communicating with the first inner cavity portion (530). The area of the cross section of the second inner cavity portion (550) in a direction away from the first inner cavity portion (530) increases gradually. An ion migration spectrometer (10) applying the abovementioned corona discharging device (50), including an ionization region (24); and a corona discharging device (50) are provided in the ionization region (24). In addition, a focusing storage electrode (14) can be used to effectively shield the corona discharging pulse interference, draw and focus sample ions; and the designed voltage control scheme realizes migration discrimination of ions and at the same time shields the ion number fluctuation caused by corona pulses, achieving the effect of stable migration spectrum lines.</p> |
