Journal ArticleDOI
Laser-induced breakdown spectroscopy detection and classification of biological aerosols.
TL;DR: In this paper, a spectrally broadband laser-induced breakdown spectroscopy (LIBS) system was used for laboratory measurements on some common biological agent simulants, which were compared to those of common, naturally occurring biological aerosol components (pollen and fungal spores) to determine the potential of LIBS for discriminating biological agents from natural background aerosols.
Journal ArticleDOI
Ambient measurements of metal-containing PM2.5 in an urban environment using laser-induced breakdown spectroscopy
TL;DR: In this article, laser-induced breakdown spectroscopy (LIBS) was used to measure the distribution of seven species in individual ambient aerosol particles during an 8-day period from 26 August to 2 September 2002 at the Pittsburgh Aerosol Supersite.
Journal ArticleDOI
Effects of focal volume and spatial inhomogeneity on uncertainty in single-aerosol laser-induced breakdown spectroscopy measurements
TL;DR: In this paper, two sets of optics were used to image different regions of a LIBS plasma and simultaneously collect spectra from single particles, and strong variation and lack of correlation between the two measurement channels suggest that emission from a single particle is localized within the plasma.
Journal ArticleDOI
Influence of particle location within plasma and focal volume on precision of single-particle laser-induced breakdown spectroscopy measurements
TL;DR: In this article, the effect of the location of particles within the plasma volume on the laser-induced breakdown spectroscopy signal for single-particle measurements is investigated, and three methods of collecting plasma emission are compared to determine the influence of plasma imaging on particle hit detection rates and signal precision.
Patent
Spark emission particle detector
TL;DR: In this paper, the authors described a method for detecting particle composition using an aerosol inlet of a particle detector, where the received particles were carried within a stream of gas and charged using a charger to have a charge.
