Abstract:

A compact electrostatic particulate collector for sampling contaminants has a collection chamber defined by a titanium inner surface of a wall. A potential inducer is disposed within the chamber to create a field potential between itself and the wall of the chamber. A blower is disposed to propel air to be sampled through the chamber. At least one rinse channel is disposed to wet the inner surface of the wall of the chamber substantially 100%. The rinse channel is angled to direct a rinse liquid in a spiral direction around the inner surface of the wall. Contaminants in the air being sampled are electro statically biased into the rinse liquid on the wall and rinsed out of the chamber for collection.
