Abstract
A particle concentrator system for the concentration of particulate material is described. The particle concentrator system comprises a prefilter module comprising a first inertial classifier configured to retain a flow in which particles smaller than a predetermined cut point size tend to segregate differentially; and a concentrator module comprising at least one second inertial classifier, and optionally more than one fluidly in series, configured to retain a flow in which particles larger than a predetermined cut point size tend to segregate differentially. The inertial classifiers are preferably virtual impactors. A gas sampler system, a gas sampler, concentrator and collection system, a method for the collection of a sample of aerosolised particulate material using such systems are also described.
