One aspect of the invention provides an automated system for performing repeated testing using an impactor which comprises a cup manifold defining multiple impaction cups, an impactor head defining transfer passages, and a nozzle manifold which defines multiple nozzles and is disposable between the cup manifold and the impactor head, so that in the assembled impactor a route is defined for through-flow via the impaction cups, the nozzles and the transfer passages. The system comprises an impaction station for performing impaction testing using the assembled impactor; a cup manifold recovery station for recovering sample material from the impactor cups in a solvent; an impactor head cleaning station; and at least one handling system for assembling the impactor for impaction, and for subsequently disassembling the impactor and delivering the cup manifold and the impactor head to their respective stations.
