Abstract
A new type of photochemical type aerosol generator of nanometersized p articles, based on UV photolysis of certain haloidaromatic compounds a nd metal carbonyls is described. The particle number concentration may be varied from 10(5) to 10(7) cm(-3) and the particle diameter from 2 to 100 nm. The temporal stability of the particle concentration and m ean diameter is about +/- 5% and +/- 10% for approximately 4 h. This g enerator can be used for calibration and adjustment of various aerosol measuring instruments individually or in combination with other devic es, such as electrostatic classifiers, etc.
