Publication number: 20160011049Abstract: A non-destructive method for chemical imaging with ˜1 nm to 10 ?m spatial resolution (depending on the type of heat source) without sample preparation and in a non-contact manner. In one embodiment, a sample undergoes photo-thermal heating using an IR laser and the resulting increase in thermal emissions is measured with either an IR detector or a laser probe having a visible laser reflected from the sample. In another embodiment, the infrared laser is replaced with a focused electron or ion source while the thermal emission is collected in the same manner as with the infrared heating. The achievable spatial resolution of this embodiment is in the 1-50 nm range.Type: ApplicationFiled: June 24, 2015Publication date: January 14, 2016Inventors: Robert Furstenberg, Chris Kendziora, Michael Papantonakis, R. Andrew McGill, Viet K. Nguyen, Graham K. Hubler

Publication number: 20140260535Abstract: A chemical detector for rapid, simultaneous detection of multiple chemicals including chemical warfare agents, toxic industrial chemicals, and explosives having one or more gas chromatography columns each with a chemosorbent or a chemo-reactive stationary phase and an infrared-transparent base, a bright infrared light source, a mechanism to direct the light source to any point along any of the columns, and an infrared sensor. Another disclosed detector has one or more gas chromatography columns each on the surface of a substrate having at least one infrared-transparent waveguide pattern, a bright infrared light source, and at least one ring resonator for each column, where each ring resonator is coated with a chemosorbent or a chemo-reactive stationary phase, and where each ring resonator spectroscopically probes the stationary phase. Also disclosed are the related methods for chemical detection.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Inventors: R. Andrew McGill, Robert Furstenberg, Viet K.

Patent number: 8421018Abstract: The present invention is directed to a method for non-contact or stand off chemical detection by selectively exciting one or more analytes of interest using an IR source tuned to at least one specific absorption band without significantly decomposing the analyte and determining if the analyte is present by comparing emitted photons with an IR detector signal made before and during or shortly after exciting the analyte. Another embodiment provides a method for non-contact or stand off chemical detection by selectively exciting one or more analytes of interest using an IR source tuned to at least one specific absorption band without significantly decomposing the analyte, wherein the analyte is excited sufficiently to generate a vapor plume, and wherein the plume is examined to detect the presence of the analyte. Additionally, the present invention provides for a system for non-contact or stand off chemical detection.Type: GrantFiled: June 5, 2012Date of Patent: April 16, 2013Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Robert Andrew McGill, Chris Kendziora, Robert Furstenberg, Michael Papantonakis, James S Horwitz, Graham K Hubler

Patent number: 8421017Abstract: A method for non-contact analyte detection by selectively exciting one or more analytes of interest using an IR source optionally operated to produce pulses of light and tuned to at least one specific absorption band without significantly decomposing organic analytes and determining if the analyte is present by comparing emitted photons with an IR detector signal collected one or more times before, during, or after, exciting the analyte. Another embodiment of the present invention provides a method for non-contact analyte detection by selectively exciting analytes of interest using one or more IR sources that are optionally operated to produce pulses of light and tuned to at least one specific wavelength without significantly decomposing organic analytes, wherein the analyte is excited sufficiently to increase the amount of analyte in the gas phase, and wherein the content of the gas is examined to detect the presence of the analyte.Type: GrantFiled: May 13, 2011Date of Patent: April 16, 2013Assignee: The United States of America, as represented by the Secretary of the NavyInventors: R Andrew McGill, Graham K Hubler, Michael Papantonakis, James S Horwitz, Chris Kendziora, Robert Furstenberg
