Deliquescent growth of inorganic-salt aerosols observed by a combined system of TDMA and integrated nephelometer

The deliquescent growth of three inorganic-salt aerosols were studied using the Tandem Differential Mobility Analyzer and Scanning Mobility Particle Sizer (TDMA+SMPS), and integrated nephelometer. The two systems were connected in parallel and operated simultaneously, and the inorganic-salt consider...

Zusammenfassung:The deliquescent growth of three inorganic-salt aerosols were studied using the Tandem Differential Mobility Analyzer and Scanning Mobility Particle Sizer (TDMA+SMPS), and integrated nephelometer. The two systems were connected in parallel and operated simultaneously, and the inorganic-salt considered were NaCl, NH sub(4)NH sub(3), and NH sub(4)SO sub(4). A comparison of the two systems showed that integrated nephelometer provides better observation on deliquescent point. However, the heat from its lamp may change the liquid state of aerosol and would delay the deliquescent point.
