Abstract:
1. An improved system for detecting and classifying submicron-sized particles in a sample taken from the environment, said system comprising an Integrated Virus Detection System (IVDS) of the type wherein the detecting means includes a differential mobility analyzer (DMA) and a condensation particle counter (CPC), wherein the improvement comprises an electrostatic collector positioned between the differential mobility analyzer and the condensation particle counter, wherein the electrostatic collector is fluidically connected to and receives the outlet air flow from the differential mobility analyzer and comprises a grounded sampling chamber having an airflow inlet and an outlet, an electrode disposed within the chamber, and a sample substrate attached to the electrode wherein an electric field between the grounded chamber and electrode focuses submicron-sized particles on the substrate for collection of submicron-sized particles from the airflow.
