First Results of the Study of Particulate Matter Samples from the Middle Urals with the Use of Secondary Ion Mass Spectrometry

First results of the study of atmospheric aerosol samples from the Middle Urals with a time-of-flight secondary ion mass spectrometer are considered. Aerosol sampling by the aspiration method on KFBZh and AFA filters is discussed. The difficulties in carrying out mass spectrometry “directly,” that is, without preliminary sample preparation, are analyzed. The results of mass spectrometry and optical microscopy of the filter surface allow us to consider prospects of their use for sampling aerosol microparticles.
