description: The given work is devoted to studying the influence of pH and spray ionization techniques on the spray current and the composition of the formed charged droplets. The research set the following objectives: 1. Development of experimental techniques and the creation of an experimental setup. 2. Investigation of the change in spray current for solutions with different pH values and identification their relationship. 3. Investigation of the field effect in a solution on the spray current. 4. Identification of the optimal spray condition to obtain the largest fraction of the spray current per analyte ions. The work was fulfilled on the premises of Ioffe Physicotechnical Institute, where necessary samples were prepared and three experimental facilities were maintained containing the studied spraying systems: a short needle, a metal capillary and a dielectric capillary. Based on the research, the results indicate that the simultaneous existence of H+ and Li+ ions in the equal concentrations reduces the spray current compared to a sample containing H+ ions only. Using of a metal capillary as an electrospray system makes it possible to obtain a larger spray current. Moreover, inside the solution dielectric and metal capillaries can be used to create an additional field which allows to direct hydrogen and analyte ions to the exit from capillary and formation of charged droplets.
