The multichannel extraction of negative charged particles from solutions of KCl, KBr, KI in glycerol and glycerol+water mixtures has been investigated by time‐of‐flight mass spectrometry. The charged particles extracted by using specially prepared perforated membranes are cluster ions consisting of deprotonated molecules of glycerol and halogen anions with several attached molecules of glycerol. The energy distribution of particles recorded by mass spectrometry is too broad for them to be the primary ions extracted from liquid. In comparison with traditional electrohydrodynamic ionization, multichannel extraction is shown to have a unique mechanism. The main factors controlling the membrane ion source, are considered, including high electric field formation, ion transport and field evaporation of ions.
