Measurement method in which a mass spectrometer is used to measure the ratio of mass to charge and the abundance of ionized entities emitted from a sample in air as a result of an inert gas being passed over the sample to pick up the molecules, which are subsequently ionized by ionized solvent droplets generated by pneumatically assisted electrospray ionization.
Note: Both positive and negative ions are observed.
