Abstract

A position control system may acquire a set of mass spectra by directing an automated positioning system to sequentially position an ionization emitter at a plurality of positions relative to an inlet of a mass spectrometer and directing the mass spectrometer to acquire, while the ionization emitter is positioned at each position of the plurality of positions, a mass spectrum of ions introduced into the inlet. The ions introduced into the inlet include ions emitted from the ionization emitter. The position control system may generate, based on the set of mass spectra, an ion intensity map representing intensity of ions introduced into the inlet of the mass spectrometer as a function of position of the ionization emitter. Based on the ion intensity map, the position control system may identify an optimum position for the ionization emitter.
