AbstractAn original scheme of a special magnetic mass-spectrometer for isotope measurements in a mass range of hydrogen–helium mixtures and their main impurities is proposed. The ion optics system contains a two-dimensional magnetic prism supplemented with two identical cylindrical electrostatic capacitors matched so that the system operates in the regime of complete triple focusing of the ion beam in two orthogonal directions and with respect to ion energies. The system ensures high dispersion and allows the mass resolution (no less than 3500) required for analysis at high brightness and a central ion trajectory length on the order of 1 m.

The interaction of cytosine with AuCl4−, under electrospray ionization mass spectrometric conditions, is discussed. On the basis of respective full scan mass spectra and product ion spectra, obtained in positive and negative ion mode, it has been deduced that cytosine is very prone to form Au(I)-containing complexes. The complexes may be formed in the gas phase by decomposition of Au(III)-containing complexes and also in the electrospray ionization source as a result of the occurrence of redox process. It has also been found that the interaction of cytosine with Au+ is stronger than that with Cu+ or Ag+, although taking into account the electrostatic attraction, it is not expected.
