Description
Nanometer particles (>100 nm) were sampled from ambient air at the Mount Soledad site. Hygroscopicity of 30 nm, 60nm and 90nm particles were measured using the HTDMA, each diameter was selected for 1 hour in that time 5 scans were made from a growth factor of 0.5 to 3.0. Volatility of 30 nm, 60nm and 90nm particles was also measured using the VTDMA each diameter was selected for an hour three different temperatures where scanned during that time (40°C, 80°C, 160°C) in between each temperature a bypass scan was taken at room temperature. Growth factors from 0.2-1.2 were measured in 10-minute scans. Particle composition was measured directly using the TDCIMS. TDCIMS runs a size selected mode for particles that are 30 nm and a bulk collection mode for particles that are under 100 nm. Particle composition is measured using chemical ionization mass spectroscopy. A NanoSMPS measure particle size distributions from 4nm to 100nm in 5-minute intervals.
