COMPARATIVE-STUDY OF THE IMPACT AND ELECTROSTATIC MECHANISMS OF THE PRECIPITATION OF ATMOSPHERIC AEROSOLS IN A THIN-WALL HOLLOW-CATHODE

Results of a comparative study of two mechanisms (impact and electrost atic) of aerosol precipitation in a new gas-discharge atomizer, namely , a thin-wall metallic hollow cathode, are presented. It is shown that the precipitation efficiency for the electrostatic method is higher t han that for the impact methods even at the highest achievable pumping rates of the analyzed air. It is suggested that both mechanisms be jo intly used for the rapid and direct determination of elements in vario us (in particle size) groups of aerosols.
