摘要

针对扫描探针显微镜与质谱联用系统中的采样方式

提出了利用原子力显微镜（AFM）探针进行电晕放电解吸附的采样方案。运用ANSYS软件对AFM导电探针进行了有限元仿真

电场分析表明间距100μm加1 kV高压时的AFM探针周围场强在0.32～62.4 V/μm间

验证了利用其产生电晕放电的可行性;通过实验观察了电晕放电现象及其规律

测得了AFM探针加高压时的伏安特性曲线

为下一步利用AFM探针产生电晕放电进行非触式采样奠定了良好的基础。

Abstract

An atomic force microscopy（AFM） probe based corona discharge sampling device for desorption ionization in scanning probe microscope mass spectrometer（SPM-MS） is put forward.Through finite element analysis

research is done on the mechanical and electrical character of the AFM probe tip.Electrical analysis shows that the field intensity around the AFM probe could achieve 0.32～62.4V/μm when the gap distance is 100 μm and the applied voltage is 1 kV

validating the feasibility and usability of the sampling device.The relationship between discharge current I and applied voltage V is studied through corona discharge experiment.These works lay a foundation for developing the corona discharge for non-contact sampling based on AFM probe.
