Design and application of multistage cascade microparticle impactor is presented. Nine-stage impactor is composed of a cascade of multi-nozzle set. Particle size distribution is in range of 15 um to 0,2 um. The impactor, pumped by 0,3 dir3/s vacuum pump, has been applied for monitoring of environmental dust contamination.
Results of ion erosion experiments performed on airborne microparticle environmental contamination are presented. A new method of microparticle depth profile analysis, based on application of sample rotation technique in SIMS analysis, is described. Sample rotation experiments, i.e. ion sputtering with application of variable azimuth incidence angle of the primary beam, are performed in order : to...
