摘要： A system and method for detecting the presence of submicron sized particles in a sample taken from the environment includes a collecting a sample from the environment and purifying and concentrating the submicron particles in a sample based on the size of the particles. The purified and concentrated particles are detected with an apparatus which includes an electrospray assembly having an electrospray capillary, a differential mobility analyzer which receives the output from the capillary, and a condensation particle device for counting the number of particles that pass through the differential mobility analyzer. The system is intended to collect a sample containing submicron size particles having a size from about 10 to about 350 nanometers and include submicron size particles selected from the group consisting of viruses, prions, macromolecules, proteins, satellites, and virus fragments. Automated controls can be utilized to control the flow of the sample through the system.

摘要： A system for detecting the presence of different size groups of submicron size particles in a fluid sample collected from the environment includes apparatus for collecting the environment. The collected a liquid sample containing submicron size particles selected from the group of viruses, prions, macromolecules, proteins and satellites, is directed to an electrospray assembly having an electrospray capillary for ejecting droplets of the fluid sample under the influence of an electric field. The ejected droplets from the electrospray assembly are directed to a differential mobility analyzer which passes the ejected droplets through an electric field, and the particles are then directed to a condensation particle device for counting the number of particles that pass through the electric field.
