description: Subject of the research: the sample collection system based on a pneumatic electrosprayer.
The purpose of the work: To investigate the influence of pneumoelectrosprayâs parameters, satellite gas on the transfer of charged droplets to the irrigated filter, as well as on the physical processes occurring during pneumoelectrospraying.
Results: The ranges of the charge values on the droplets formed during pneumoelectrospraying were evaluated, provided that the resulting aerosol was fully charged. A group of dependences of the total pneumatic electrospray current on the spray voltage for various volumetric fluid flow rates in the system is found. The dependences of the sprayer current on the volumetric flow rate of the liquid (water) were obtained Itot=Itot(Q) for different values of the voltage at the sprayer (see Fig. 11). The system parameters for which the sample is effectively collected (see fig. 12) were found experimentally. Namely, the combinations of distances x (between the pneumosprayer and the grid) and y (between the grid and the irrigated filter), at which the greatest amount of sample is accumulated in 15 minutes, were identified: x = 2 cm and y = 7 cm; x = 3 cm and y = 8 cm; x = 4 cm and y = 9 cm. On the base of our experiment, theoretically we estimate the range of volumeâs values (the volume that accumulated in 15 minutes) under the conditions that we set (see section 4.2. of this workâs practical part). The value of this volume is in the range of 0,168-55,2 Âµl. The concentration of the test substance in the resulting solution was evaluated. Its value exceeds 10â7 mol/l, which makes it possible to use the mass spectrometric method ERIAD for analysis.
Scope of using results of the work: sample preparation devices for analyzing traces of toxic substances in the air of production premisesâ working zone by the mass spectrometric method ERIAD.
