Short summary
We present a proof-of-concept method of concentrating aerosols in a continuous stream using an applied electric field. Potential enrichment was estimated using a trajectory model, predicting values of up to 65 % for 75–200 nm aerosol, using voltages of up to 30 kV. Experimental results using similar geometry yielded up to 15 % observed enrichment for the same conditions. These results imply that aerosol enrichment using an applied electric field can be achieved in continuous-flow applications.
