From: Real-time assessment of cigarette smoke particle deposition in vitro
British American Tobacco’s standard exposure chamber used for in vitro exposures to whole smoke at the ALI [A], and a schematic cross-section [B]. For extraction of deposited particulate matter for spectrofluorescence analysis, * illustrates the level reached by 2 ml extraction solvent when added to the exposed cell culture insert, rising 0.56 cm up the inner wall (diagram adapted from [11]).
