Abstract:
Polydisperse dioctyl phthalate (DOP) aerosols are employed for testing filter penetration with loading of R- and P-series particulate filters for National Institute for Occupational Safety and Health (NIOSH) certification. Penetration for filters must not exceed NIOSH allowed maximum levels during the entire loading of 200 mg DOP indicating no filter degradation. Degradation of respirators loaded with DOP by other aerosols as well as respirators exposed to both oil and non-oil aerosols found in some workplaces is not well studied.

Traditional aerosol samplers are limited in their abilities to collect large quantities of particulate matter due to their low flow rates, high pressure drops, and are noise intrusiveness. The goal of this study was to develop an alternate aerosol sampler using electrostatic precipitation technology that was safe and not noise intrusive to be deployed in homes. The O-Ion B-1000 was selected as the most suitable electrostatic precipitator (ESP) for achieving the goal of this study because of its affordability, the design of its collection electrode and its high flow rate.

While electrostatic effects are well known and can be observed all around us, it remains among the most poorly understood areas of physics. Pharmaceutical aerosols delivered by dry powder inhalers (DPIs) are known to carry bipolar charges that may influence lung deposition. Although the relationship between the magnitude and polarity of charges on total and regional lung deposition in human subjects is unclear, an important step towards understanding this relationship requires the accurate measurement of pharmaceutical aerosol charges.

Dry powders for inhalation, although clinically effective, tend to be inefficient in terms of the extent and reproducibility of drug delivery. In part at least this is due to an inadequate understanding of the relevant particle-particle interactions between drug and drug, and drug and carrier. Electrostatic charge interactions are one of several factors influencing the overall efficiency of an inhalation powder. The practical significance of such interactions is considered to be critical in every aspect of the powder formulation, including the formation of an ordered mix and, more importantly,

Cascade impactors, routinely used for in vitro particle size characterization of pharmaceutical aerosols, are calibrated using dilute, charge-neutralized, monodisperse aerosols. But pharmaceutical aerosols are known to generate concentrated, inherently charged, polydisperse aerosol clouds. A computational model of the Andersen Cascade Impactor (ACI) suggested that the presence of charge on aerosol particles may influence their deposition within the ACI, but experimental validation of the model is warranted.

Rutile tin oxide (SnO2) is a wide band gap (3.6 eV at 300K [1]) n-type semiconductor material. It is widely used as sensing elements in gas sensors [2]. The sensing mechanism is generally attributed to the significant change in the electrical resistance of the material associated with the adsorption/desorption of oxygen on the semiconductor surface [3]. The formation of oxygen adsorbates (O2− or O−) results in an electron-depletion surface layer due to the electron transfer from the oxide surface to oxygen [4]. Recent studies [5, 6] have shown that use of tin oxide nanocrystals significantly i
