US Patent:

8564776, Oct 22, 2013

Filed:

Oct 12, 2010

Appl. No.:

12/903003

Inventors:

Steven W. Graves - San Juan Pueblo NM, US
Robert C. Habbersett - Santa Fe NM, US

Assignee:

Los Alamos National Security, LLC - Los Alamos NM

International Classification:

G01N 21/00

US Classification:

356338

Abstract:

A system and method for analyzing a particle in a sample stream of a flow cytometer or the like. The system has a light source, such as a laser pointer module, for generating a low powered light beam and a fluidics apparatus which is configured to transport particles in the sample stream at substantially low velocity through the light beam for interrogation. Detectors, such as photomultiplier tubes, are configured to detect optical signals generated in response to the light beam impinging the particles. Signal conditioning circuitry is connected to each of the detectors to condition each detector output into electronic signals for processing and is designed to have a limited frequency response to filter high frequency noise from the detector output signals.
