Halley's comet dust particle elemental composition as function of dimension was estimated. It is possible to subdivide particles into: dust particles with approximately chondritic ratio for major elements; dust particles with excess of carbon organic compounds; dust particles with anomalous ratios for major elements; troilite grains; and exotic particles (for example, excess of Na, Cl). The noticeable part of the spectra, which corresponds to small particles, is not the oxygen peak. It may reflect the behavior of plasma clouds with low density. The noticeable part of small particle spectra have higher ratios Mg/Si,Fe/Si,Al/Si in comparison with large particle spectra. The nature of this effect can be connected with the response function of the instrument or with excess of specific substances in small particles
