Patent ID: 6964189

Claim:
A portable, compact, aerosol contaminant extractor comprising: a) a housing with inlet and outlet ports for admitting air to be sampled and discharging same after sampling; b) an ionizer for charging aerosols in the air which passes therethrough from said inlet port; c) a removable collector substrate having a plate-like surface for collecting charged aerosols and ground plates, said collector substrate being positioned between and spaced apart from the ground plates, said plates being parallel to each other and being positioned so that air which has passed through the ionizer will pass between said plates, said collector substrate being maintained at a potential sufficiently higher than ground to effect the collection of charged aerosols; d) power supply means for maintaining high voltage for said ionizer and for said collector substrate; e) means for moving the air through said inlet, ionizer, ground plates and collector substrate at a measured rate and discharging same through said outlet port; f) an access port in said housing positioned so that when opened, said collector substrate may be removed so that aerosols collected on the surface of said substrate may be analyzed; and g) storage means within said housing to store additional collector substrates.
