Atmospheric Size Distributions Measured by Differential Mobility .
A differential mobility and optical particle size spectrometer (DMOPSS) was developed to measure ambient size distributions based on geometric particle diameter in the size range of 0.1 to 1.0 μm diameter. The DMOPSS consists of a high-flow differential mobility analyzer (HF-DMA) followed by an optical particle counter.

Aerosol mass spectrometry - Wikipedia
Aerosol mass spectrometry is the application of mass spectrometry to aerosol particles. Aerosol particles are defined as solid and liquid particles suspended in a gas (air), with size range of 3 nm to 100 μm in diameter. Aerosol particles are produced from natural and anthropogenic sources, through a variety of different.

The particle distributions over these classes can be monitored as a function of time and particle size range. Definition of the particle classes as used for on-line evaluation is performed in an earlier step, either by manual approach, or by selection from a particle class database, or, as in most cases, by fuzzy clustering of a set.
Ultrasonic Measurements in Particle Size Analysis - Sonozap
The particle size distribution and concentration of a col- loidal dispersion can be determined by measuring its ultrasonic velocity and/or attenuation coefficient as a func- tion of frequency and then using a suitable mathematical model to interpret the spectra. Ultrasonic spectroscopy can be used to analyze particle sizes.
