The invention relates to low flow rate cascade impactors for sampling aerosols notably but not limited to pharmaceutical aerosols The impactor stages serve as both orifice plate and collecting cup simplifying collection and analysis The impactor is designed to operate at flow rates approximating the inspiratory flow rates of young children and infants...

Cascade Impactor

The cascade impactor as its name implies is a series of impactor plates connected in series or in parallel Fig 1157 The diameters of the nozzles or slits above each impactor plate become increasingly smaller as the air moves through the impactor so that the air moves increasingly faster through these orifices and smaller and smaller particles impact on the plates see Eq...

Application of the Cascade Impactor to Studies of

The cascade impactor was devised by MAY for the sampling and particle size determination of aerosols containing droplets larger than 1 micron Four jets in series each discharge against a glass slide The orifices of successive jets diminish in area so that as the air-borne particles are drawn through the cascade they are discharged at a higher velocity at each succeeding stage and on that...
