Testing a Paul trap through determining the evaporation rate of levitated single semi-volatile organic droplets Valenzuela, A. Rica Alarcón, Raúl Alberto Olmo Reyes, Francisco José Alados Arboledas, Lucas Rigorous knowledge of the optical fingerprint of droplets is imperative for the understanding of complex aerosol processes. Here, a Paul trap is operated to store single semi-volatile organic droplets in air. The droplets are illuminated with a green laser and the elastic scattering is collected on a CMOS camera. The setup provides excellent performance in terms of confinement and stability, allowing us to detect size changes of the order of few nanometres. The stability also allows us to measure vapour pressures with remarkable reproducibility. This approach supplies a robust method for the optical interrogation in the sub-micron range. 2021-02-04T10:47:59Z 2021-02-04T10:47:59Z 2020-11-09 info:eu-repo/semantics/article Valenzuela, A., Rica, R.
