ABSTRACT:
The present invention is an electrostatic collector for low cost, high throughput, high efficiency sampling and concentration of bioaerosols. The device is small enough to be portable and can be contained within or placed on the wall of a typical office or hospital building. The collector comprises one or more collector modules, each having an ionizing electrode, a conical outer electrode, a wet collection electrode, and a liquid collection system. Airflow through a collector module may be partially blocked to enhance the collection of smaller particles and the collection electrode may comprise multiple, programmable electrodes to focus particle deposition onto a smaller area. Particles are collected into a small volume of liquid to facilitate subsequent analysis by an attached analyzer or at a remote site.
