Measurements of the element composition of the dust particles in Comet Halley were made by the PUMA-1 and PUMA-2 instruments onboard the VEGA spacecraft. The time-of-flight analysis of ions produced by the hypervelocity particle impact on the target was applied with a wide (W = 100 eV) and a narrow (W = 20 eV) energy window of the instruments. The analysis of measured spectra shows that the mass resolution for "small" particles (Q < 10-13 C) was high enough in both modes to separate individual mass lines. For large particles the resolution did not change for the narrow window, it decreased, however, for the wide one (to about 50). A relative transmission Qw/Qn dependence on the mass number for the wide and narrow window made has been found.
