Figure 10From: Rat pulmonary responses to inhaled nano-TiO2: effect of primary particle size and agglomeration state Experimental set-up for the generation of small agglomerate aerosols. Experimental set-up using three nebulizers in parallel to produce aerosols essentially composed of small NP agglomerates. ELPI: electrical low pressure impactor; HEPA filter: high-efficiency particulate air filter.Back to article page
