Primary Determination of Particle Number Concentration with Light Obscuration and Dynamic Imaging Particle Counters
Accurate number concentrations of particles in liquid media are needed to assess the quality of water, pharmaceuticals, and other liquids, yet there are limited reference materials or calibration services available with clear traceability to the International System of Units. We describe two methods, based on very simple modifications of commercial particle counter instruments, that can provide...
متن کاملEfficiency of light-scattering aerosol particle counters.
The counting efficiency as a function of particle size has been calculated for a particular forward scattering aerosol particle counter that uses white light illumination for spherical particles with indexes of refraction 1.33-0i, 1.40-0i, 1.50-0i, 1.592-0i, 1.50-0.05i, 1.50-0.1i, 1.50-0.5i, and 1.95-0.66i. The counting efficiency differs from 100% because of statistical effects: photoelectron ...
متن کاملContinental anthropogenic primary particle number emissions
Atmospheric aerosol particle number concentrations impact our climate and health in ways different from those of aerosol mass concentrations. However, the global, current and future anthropogenic particle number emissions and their size distributions are so far poorly known. In this article, we present the implementation of particle number emission factors and the related size distributions in ...
متن کاملSpin determination of particle unstable levels with particle correlations
Experiments with rare isotope and with stable beams offer important opportunities to explore the structure of nuclei near and beyond the proton and neutron drip lines. This structure information includes the energies, spins, and parities of nuclear levels near the drip line as well as the probabilities for their formation and decay; such information guides theoretical modeling of the interactio...
