In this study, a serial methodology is presented for estimating the effective density of ambient sub-micron aerosol employing lab-made 1 stage low-pressure impactor of Hyun et al. (2015) and SMPS (Scanning Mobility Particle Sizer) together. The effective density from this methodology (Impactor+SMPS) was compared with another methodology (BAM+SMPS) for estimating the effective density employing BAM (Beta-Attenuation Monitor) and SMPS. As a result, the effective density obtained with impactor+SMPS ranged from 0.42 g/cm3 to 2.36 g/cm3, while the effective density obtained with BAM+SMPS ranged from 1.01 g/cm3 to 1.72 g/cm3. The difference between these results might be caused by the particle loss in the impactor.
Abstract
In this study, a serial methodology is presented for estimating the effective density of ambient sub-micron aerosol employing lab-made 1 stage low-pressure impactor of Hyun et al. (2015) and SMPS (Scanning Mobility Particle Sizer) together. The effective density from this methodology (Impactor+SMPS) was compared with another methodology (BAM+SMPS) for estimating the effective density employing BAM (Beta-Attenuation Monitor) and SMPS. As a result, the effective density obtained with impactor+SMPS ranged from <TEX>$0.42g/cm^3$</TEX> to <TEX>$2.36g/cm^3$</TEX>, while the effective density obtained with BAM+SMPS ranged from <TEX>$1.01g/cm^3$</TEX> to <TEX>$1.72g/cm^3$</TEX>. The difference between these results might be caused by the particle loss in the impactor.
