A corona discharge ionization source is designed for planar FAIMS,which consists of corona needle,molybdenum mesh,copper base and PTFE cylinder. The corona needle is made from tungsten wire with a diameter of0.5 mm through electrolytic processing with conditions setting as electrolysis voltage at 6 V,the electrolyte Na OH( 1 mol/L) and duration time160 s. The voltage-current characteristics of the corona discharge ionization source were observed at pin-grid distance between 2 mm ~ 8 mm,where the correlation between discharge voltage( kV) and the current/voltage( μA/kV) is approximately linear. The FAIMS spectra of DMMP were measured at discharge currents between 1 μA ~ 40 μA,which can be observed that both the reaction ion peak and the DMMP ion peak increased with the discharge current.
