A gas pycnometer /microliter/ for determining the mean density of atmospheric aerosol particles
Abstract
The physical principle of a gas pycnometer is explained with fundamental considerations about the accuracy of measurement. A pycnometer has been developed with which volumes of 2 to 2.5 cu mm can be determined within an error of 10%. Mean densities of samples of dry atmospheric aerosol particles from various locations vary between 1.8 and about 3 g/cu cm.
