Size Determination of Aerosol Particles by Owl Spectrometer

Calibration of the Passive Cavity Aerosol Spectrometer Probe for Airborne Determination of the Size Distribution

This work describes calibration methods for the particle sizing and particle concentration systems of the passive cavity aerosol spectrometer probe (PCASP). Laboratory calibrations conducted over six years, in support of the deployment of a PCASP on a cloud physics research aircraft, are analyzed. Instead of using the many calibration sizes recommended by the PCASP manufacturer, a relationship ...

Real-time, Size-resolved, Quantitative Measurements of Diesel Exhaust Particles Semi-volatile Chemical Composition by Means of Aerosol Mass Spectrometer

Atmospheric aerosols and particulate matter from a wide variety of emissions sources measurements are conventionally performed by recording PM mass. The ambient standards are written in terms of mass concentrations, and emission regulations are based on mass rates. However, in order to understand better the nature of the mobile source contribution to ambient PM, many research groups are current...

Size Distribution Characterization Of Outdoor Aerosol Particles

Mass size distributions of atmospheric aerosol particles were measured at four different regions in outdoor of El-Minia governorate (Upper Egypt). The study was conducted during March 2012 to March 2013. Measurements were performed using low pressure Berner cascade Impactor as an aerosol sampler. The Impactor operates at 1.7 m3/h flow rate with aerodynamic "cut-off" size range from 0.06 up to 1...

Determination of Aerosol Particle Size Distribution using Electrical Differential Mobility Analyzer (DMA)

Introduction: Determining the size distribution of the particles for assessing their effects on human health and their control mechanisms is very effective. One of the most important equipment used in determining particle size distribution is the DMA. In this study, in addition to the design and construction of a DMA, the size distribution measurement of aerosol particles was carried out. Mate...
