Measurement of nonvolatile particle number size distribution

Primary Particle Size Distribution Measurement of Nanomaterials by Using TEM

Industrial applications of nano-particles are reported in many fields recently. Regulation of nano-materials is also discussed in Organization for Economic Co-operation and Development (OECD). European Union (EU) announced the definition of nano-material in 2012. According to EU definition, nanomaterial means a natural, incidental or manufactured material containing particles, in an unbound sta...

Measurement of Particle Size Distribution by Acoustic Emission Method

Continuous measurement of size distribution of particles is the necessary parameter regarding the control of some specific production processes. A possible solution is the use of the acoustic emission method which is based on the measurement and analysis of pressure pulses generated by an impact of solid particles against a solid obstacle. Our paper focuses on the practical verification of the ...

The measurement of particle size distribution using the Single Particle Optical Sizing (SPOS) method

A new technique for measuring the Particle Size Distribution (PSD) of a soil, known as Single Particle Optical Sizing (SPOS), has been evaluated. A series of tests were conducted to compare the results obtained from sieve analysis and the SPOS method. It was found that for typical laboratory sands, the SPOS method oversizes particles compared to sieving by 20-30%, as predicted by theoretical an...
