| Popis: | A glowing metal wire-based nanoparticle aerosol generator has been developed in this work. Two metal wires of different chemical compositions have been used for generation of aerosols. It has been found that generator could produce a stable concentration of aerosol particles of the order of 107 per cm3 for operating parameters determined from control experiments. Size distribution analysis showed aerosols in nanoparticle region (geometric mean ≈ 15 nm) with geometric standard deviation of ≈1.4. TEM analysis revealed that the primary aerosol sizes could be lower than 10 nm. This affordable, low-power, easy-to-use aerosol generator can provide a stable continuous source of high concentration of very small nanoparticles suitable for use in fundamental studies on particle formation and dynamics as well as for the synthesis of metal nanoparticles for specific purposes. |
