Particle size distributions and concentrations of airborne endotoxin using novel collection methods in homes during the winter and summer seasons

In that study sampling methods for airborne endotoxin are compared in order to find a standard method . The feasibility of liquid impingers and MOUDI (micro-orifice uniform deposit impactor) for airborne endotoxin collection was demontrated , then these methods were compared to the filter cassette sampling method and finally the performance of these sampling methods in variable realistic conditions was validated.
