It is shown that the temperature of the desolvating capillary of the electrospray ionization source has a significant impact on the formation of complexes of cyclic oligosaccharides with proteins and metals. The complexes with proteins undergo decomposition upon temperature rise. Simultaneously complexes with metals consisting of several metal atoms and a few molecules of sugar appear. Besides novel oligosaccharides complexes with cations of metals in high oxidation states (Th4+) and noncovalent complexes of DNA primers with several molecules of beta-cyclodextrin have been obtained.
