“…In previous studies, Iida et al (2014) and Dougherty et al (2007) adjusted the mass concentration of the solute in the solution in order to control the size of the generated particles in inkjet aerosol generator. The relationship between solute concentration and particle size was investigated experimentally (Dougherty et al 2007;Iida et al 2014).…”

“…Using a VOAG, 3-20 mm sized fluorescent liquid oleic acid aerosol particles were generated (Kesavan et al 2008). However, there are some problems with the VOAG: (1) the orifice is clogged frequently, (2) the generated particles contain some doublets (Iida et al 2014), and (3) aerosol particles are affected by high pressure (Eisenberg et al 2011). The above-mentioned aerosol generators have limits to generate aerosols with high concentration of monodisperse particles.…”

We investigated the effect of inkjet operating parameters on the size control of aerosol particles. Droplets with agglomerates of polystyrene latex particles were generated from an inkjet nozzle and continuously dried up at the temperature of 38 C. When droplets have the size range of 30 to 70 mm in diameter, aerosol particles with the size range of 3.5 to 7.1 mm were generated after the drying process. We controlled the particle size easily within a factor of two by adjusting rising/falling time and voltages of an actuating waveform. Generated particles were shown to have a narrow particle size distribution. Thus, the particle concentration of aqueous suspension does not need to be adjusted precisely in order to control the size of generated aerosol particles.

“…The jet of liquid leaving a nozzle typically breaks down into a single droplet with the possible formation of one or more satellites (Bottiger and Deluca 1999;Hoath et al 2012, Hoath et al 2013. Because a single primary droplet is produced each time an electrical pulse is applied, ink jet cartridges have been used for aerosol generation (Bottiger et al 1998;Bottiger and Deluca 1999; 2000; Sergeyev and Shaw 2006;Yli-Ojanperä et al 2012;Iida et al 2013;Udey et al 2013). …”

Aerodynamic particle sizer (APS) users typically calibrate the particle sizing capabilities, but not the counting efficiency upon which aerosol concentration results are based. Herein, comparisons were made between the counts provided by an ink jet aerosol generator (IJAG) with those measured by an APS. Near-monodisperse (geometric standard deviation of about 1.06) liquid or solid aerosols in the size range of 0.95 to 13.3 μm aerodynamic diameter (AD) generated with an IJAG were released into the inner inlet-tube of the APS in a manner that rendered APS wall and aspiration losses negligible. For most experiments, the IJAG generated 75 particles/s, which rate was maintained by the IJAG system through control of electrical pulses applied to its ink jet cartridge. For particles in the size range of 2-13.3 μm AD, the ratio of relative detection efficiency (ratio of the number of particles counted by the APS to the number reported as generated by the IJAG) was 99.3 ± 1.4%; however, for test particles between 0.95 and 2 μm AD, the relative detection efficiency was somewhat lower, but the drop off was less than about 2%. This slight drop off is likely associated with the light scattering detection approach and corresponding counting algorithm of the APS. Tests were conducted where the IJAG produced 7.0 μm AD particles at rates of 1 to 500 s -1 and the results showed essentially a 1:1 correspondence between IJAG and APS counts. The presence of smaller-sized background particles did not affect the measured APS counts of larger-sized challenge particles.
