Abstract

Aperture coding has been utilized in mass spectrometry to enable miniaturization of the instrument while maintaining resolution and throughput. In miniature cycloidal mass spectrometry, implementing aperture coding is difficult since uniform magnetic and electric fields are required in the sector region. This work shows through finite element simulation that the compatibility between a cycloidal mass analyzer and aperture coding has been improved by the development of a novel electric sector. COMSOL 5.2a was utilized as the primary finite element analysis tool, and MATLAB R2016b was used to generate most figures.
