Abstract. Trace elements concentrations were determined in shallow snow samples from 21 sites in the Italian Eastern Alps in order to identify the sources of the contaminants present in the tropospheric winter boundary layer. The collection of superficial snow layers was carried out weekly at altitudes between 1000 and 3000 m next to meteorological stations, far away from villages, roads and ski slopes. Ultra clean procedures were adopted in order to avoid contamination of the snow during the different experimental phases. Trace elements (Ag, Ba, Bi, Cd, Co, Cr, Cu, Fe, Mo, Mn, Pb, Sb, Ti, U, V and Zn) were determined by Inductively Coupled Plasma Sector Field Mass Spectrometer (ICP-SFMS). Ancillary parameters such as major ions (SO42−, NO3−, Ca2+;, Mg2+, K

Mass Spectrometers

In calculating the resolving power of a homogeneous field mass spectrometer, one must consider the dispersion and the beam width of the instrument. The latter is the sum of at least 10 components, which are discussed. Formulae giving the resolving power of three types of spectrometer of current interest are developed, as well as formulae for positioning the exit slits.
