    摘要: A small area electrostatic aerosol collector includes a collector housing, an inlet nozzle that extends from the housing and an exit port that provides an exit for air to flow back out of the housing. A pumping arrangement pulls air into the housing through the inlet nozzle. The sampled air is moved through ductwork such that particulates are collected on a substrate and the air is evacuated through the exit port after collection. The collector includes a charging device positioned within the ductwork to create an electric field defining a charging point that the air passes through between the inlet nozzle and the substrate. The substrate is held at a neutral or opposite charge relative to the electric field created by the charging device. Particulates are collected on the sample substrate by containing the aerosol in a small area and by forcing the aerosol to flow near the substrate.

    摘要: A small area electrostatic aerosol collector combines electrostatic collection of aerosol particles and electrohydrodynamic spraying of fluid so that a sample collected electrostatically can have fluid applied thereto. The fluid may assist with disaggregation and/or desalinization of biological material collected onto a sample substrate. A controller associated with the collector may control an electrostatic charge device and a spraying device such that the charge device and spraying device may operate in alternating fashion, or the charge device and spraying device may operate simultaneously. Further, mechanical systems are provided, for the disaggregation of particulate clusters collected onto a sample substrate.

    摘要: A biological and chemical detection system is provided that detects and identifies biological and/or chemical particulates of interest. The biological and chemical detection system comprises a collector, a first optical device, a second optical device and a processor. The collector is configured to deposit particulates drawn from a fluid stream onto a sample substrate to define a sample area. The first optical device derives first data relative to at least a portion of the sample area, which is analyzed to determine at least one field of view and/or specific target location. The second optical device then interrogates the sample area at each determined target location, e.g., using Raman spectroscopy, to produce interrogation data. The processor determines whether the sample area includes predetermined biological or chemical particulates of interest based upon an analysis of the interrogation data and triggers an event such as an alarm or message if the predetermined biological or chemical particulates of interest are identified.
