Popis:	This work represents a more precise study of the characteristics of A1XA2+ ions in the gas phase, which can be formed in concentrated electrolyte solutions. In order to obtain the parent ions A1XA2+, a simple system was used, a mixture of two-alkali halide salts in an aqueous solution. In this system, A1+, A2+ are Li+, Na+, K+, Rb+, Cs+ and X- is F-, Cl-, Br-, I-, respectively. Utilizing Fast Atom Bombardment (FABMS) measurement methods, an A1XA2+ ion type in the mass spectra was obtained, and from this resulting spectrum, an ion was selected to be used as a precursor ion for the next stage. In this way, the Collisionally Activated Dissociation (CAD) spectra were obtained and the product ions identified.
