Title:
A METHOD AND APPARATUS FOR DILUTION OF AEROSOLS
Document Type and Number:
WIPO Patent Application WO/2014/202771
Kind Code:
A3
Abstract:
The invention provides an apparatus set up for diluting aerosols; the apparatus comprising: (i) a dilution chamber (1); (ii) an aerosol inlet (2) on one side of the dilution chamber for admitting an aerosol into the dilution chamber; (iii) an aerosol outlet (3) on the same or another side of the dilution chamber through which diluted aerosol particles can leave the dilution chamber; (iv) a diluent gas inlet (4) for admitting into the chamber a diluent gas; (v) a diluent gas outlet (5) through which diluent gas can leave the dilution chamber; (vi) a gas flow maintenance system (6) that provides circulation of the diluent gas through the dilution chamber; and (vii) means for determining the extent of dilution of the aerosol leaving the aerosol outlet. The invention also provides methods of diluting and counting aerosol particles using the apparatus of the invention.
