Electrospraying conductive solutions in normal conditions with a wide volume flow velocity range

The production of charged particles (ions, clusters) from fluid in a strong electric field while in normal conditions was experimentally studied using a dynamic liquid flow splitter on the meniscus. The existence of non-droplets regimes for obtaining charged particles for liquid flow rates up to 1000 μl/min, solute concentrations up to 1 M and acid content in solution up to 1 % was displayed. Depending on the experimental conditions the existence of a "classic" fluid electrospraying regime in normal conditions in air and a non-droplets regime were demonstrated for obtaining charged particles current. The performance of an ion mobility spectrometer with Bradbury-Nielsen gate is demonstrated in a non-droplets regime of obtaining charged particles using the example of the suspension of human cells epidermoid carcinoma A431. The cells concentration in the suspension is 1 ppm.
