设计了一种小型针-柱电晕放电结构,实现了敞开式离子源和微型气泵的系统集成。通过数码相机拍摄的针-柱放电图像和示波器记录的特里切尔放电波形,验证了该针-柱结构在没有外界气流、间隙仅2 mm的实验条件下实现了稳定的电晕放电。对针-柱结构电晕放电特性进行了研究,讨论了放电电压、镇流电阻、柱直径大小、针-柱间距等参数对针-柱电晕放电的影响,通过伏安特性曲线分析得出在放电电压为-3 800 V、镇流电阻为10 MΩ、柱直径为4 mm、间距为2 mm的实验条件下,产生的离子风气体流速最大(采用testo 405-V1风速仪测得最大气体流速为1.15 m/s)。该针-柱结构可采用微机电系统(MEMS)工艺加工实现,有望应用于质谱仪、离子迁移谱、高场非对称波形离子迁移谱等便携式分析仪器中,实现敞开式离子源和微型气泵的双重功能。
A micro needle-to-cylinder corona discharge structure was designed to integrate an ambient ion source and a micro air pump. By needle-to-cylinder discharge photos and Trichel discharge waveform recorded with a digital camera and an oscilloscope respectively
it verified that the stable corona discharge of needle-to-cylinder structure could be realized without external air flows and with only 2 mm distance between need and cylinder. The corona discharge characteristics of the needle-to-cylinder structure were researched and the influence of experimental parameters
like discharge voltages
ballasting resistor
the diameter of cylinder and the distance between the needle and cylinder
on the corona discharge was discussed. By analysis of the volt-ampere characteristic curves
it shows that the max velocity ionic wind can be gotten in a discharge voltage of -3 800 V
a discharge resistor of 10 MΩ
a cylinder diameter of 4 mm
and the distance between the need and cylinder of 2 mm. Moreover
the max air flow velocity is 1.15 m/s measured by the test 405-V1 anemometer. The needle-to-cylinder structure can be fabricated by Micro-electro-mechanical System(MEMS) technology
and may be used in the portable analytical instruments to realize the double functions of ambient ion source and micro air pump
such as mass spectrometry
ion mobility spectrometry
and high-field asymmetric waveform ion mobility spectrometry.
