A Guide to Choosing a Particle Sizer
The choice of a particle size analyzer has never been more difficult. There are several techniques from which to choose and variations within each technique. Sales literature claims of specification and performance have become highly inflated, confusing the first-time buyer; the result has been to hinder and not help the decision making process. Many particle sizing instruments were originally ...
متن کاملComparison of the Grimm 1.108 and 1.109 portable aerosol spectrometer to the TSI 3321 aerodynamic particle sizer for dry particles.
This study compared the response of two optical particle counters with that of an aerodynamic particle sizer. The optical particle counters rely on the amount of incident light scattered at 90 degrees by a particle to measure particle number concentration by optical particle size. Two models of optical particle counters from Grimm Technologies were used: the portable aerosol spectrometer (PAS) ...
متن کاملAn influence matrix particle – particle particle - mesh algorithm with exact particle – particle correction
The classical N -body problem consisting of the interaction of N computational particles, is the key computational issue in a number of diverse fields of science including chemistry, fluid dynamics, and astrophysics. For particles interacting through long range potentials the direct evaluation of their mutual interaction nominally scales as OðN Þ. In order to reduce this computational cost a si...

متن کاملNotably improved inversion of differential mobility particle sizer data obtained under conditions of fluctuating particle number concentrations
The differential mobility particle sizer (DMPS) is designed for measurements of particle number size distributions. It performs a number of measurements while scanning over different particle sizes. A standard assumption in the data-processing (inversion) algorithm is that the size distribution remains the same throughout each scan. For a DMPS deployed in an urban area this assumption is likely...
