Abstract:
1. A small area electrostatic aerosol collector comprising: a collector housing; an inlet nozzle that extends from the collector housing to provide an inlet for air to flow from outside of the collector housing to the inside of the collector housing; a sample substrate receiving area within the collector housing; a passageway for air to flow from the inlet nozzle to the sample substrate receiving area, the passageway extending perpendicular from the sample substrate receiving area; a charging device having an electrode that extends into the passageway at an angle non-parallel to the passageway such that the tip of the electrode is generally centered in the passageway; and a high voltage power source coupled to the charging device; wherein, a sample substrate having a collection surface is positioned in the sample substrate receiving area and a sample operation is performed such that:
