ABSTRACT:
Samples of fine dusts in air or gases are collected for analysis and measurement by atomic absorption or atomic fluorescence by conducting the air or gases across a surface of a sample container and causing the dust to be deposited electrostatically on the said surface. The sample container is then heated to a temperature sufficient to vaporize the particles of dust, and the vaporized particles are then brought into the beam path of an atomic absorption or atomic fluorescence spectrometer.
