First Claim
Patent Images
1. A system for collecting particles and transporting the collected particles, the system comprising:
- a source of sample dispersed in a gas or liquid medium;
a concentrator in communication with the source and adapted to collect the sample, wherein the concentrator is an electrostatic precipitator;
a traveling wave grid extending from a first location at which the concentrator is located, to a second location;
wherein upon operation of the concentrator and the traveling wave grid, sample is collected from the medium and transported to the second location.

Abstract
Particle collection, transport, and detection systems are disclosed. The systems are uniquely adapted for collecting or concentrating particles from a flowing medium and then transporting the collected particles to a desired location or for subsequent analysis. Electrostatic traveling wave grids can be used in conjunction with sample concentrators.
