Method And Assembly For Gas Detection Via A Convergent Birefringent Filter

View page
US Patent:
6576905, Jun 10, 2003
Filed:
Jun 14, 2001
Appl. No.:
09/881644
Inventors:
Harold S. Lessure - Pittsburgh PA
Richard A. Evans - Pittsburgh PA
Richard P. Kunkle - Irwin PA
Dale M. Matuza - Murrysville PA
Assignee:
Gas Research Institute - Des Plaines IL
International Classification:
G01B 902
US Classification:
2503385, 25033907, 25033908, 356346, 356352
Abstract:
An assembly and method provide sensitive high speed spectroscopic gas detection via the use of a non-collimated convergent light path through a birefringent crystal in a birefringent filter design to allow improved light collection and a reduction in the number of optical elements required to produce a useful absorption signal for the detection of gases.

Wide Concentration Range Gas Detection

View page
US Patent:
7592595, Sep 22, 2009
Filed:
Oct 6, 2006
Appl. No.:
11/545004
Inventors:
Harold S. Lessure - Pittsburgh PA, US
Satoru Simizu - Pittsburgh PA, US
Kirankumar M. Kothari - Hoffman Estates IL, US
Assignee:
Operations Technology Development, NFP - Des Plaines IL
International Classification:
G01J 5/58
US Classification:
25033901
Abstract:
A method and apparatus in which a first absorption measurement is made over a first frequency interval or set of frequency intervals including one or more absorptions from a spectral band of interest. The first absorption measurement is ideally selected to be near the frequency of a peak in the absorption spectrum, providing high sensitivity at low gas concentrations. A second absorption measurement is made over a second frequency interval. The second absorption measurement is made to include a contribution from the broadening of the absorption spectrum at higher concentrations. The second absorption measurement provides sensitivity at higher concentrations. The two absorption measurements are then combined to deduce the target sample concentration as the absorption line spectrum changes shape with concentration.

Non-Dispersive Infrared Gas Analyzer With Interfering Gas Correction

View page
US Patent:
58863486, Mar 23, 1999
Filed:
Feb 14, 1997
Appl. No.:
8/801942
Inventors:
Harold S. Lessure - Pittsburgh PA
Satoru Simizu - Pittsburgh PA
Louis J. Denes - Pittsburgh PA
Alberto M. Guzman - Pittsburgh PA
Assignee:
American Intell-Sensors Corporation - Pittsburgh PA
International Classification:
G01N 2135
US Classification:
25033913
Abstract:
An infrared gas analyzer for measuring low concentrations of a target gas, on the order of parts per million, in a sample gas is comprised of a gas sampling chamber, an infrared light source, and a power source for energizing the light source. A plurality of filters is provided to transmit infrared radiation at certain wavelengths. The wavelengths are chosen such that the effects of unwanted gases (such as water and carbon dioxide) can be removed from the final output signal. A plurality of infrared detectors are responsive to the filters for producing a plurality of electrical signals. A circuit is provided for combining the plurality of electrical signals to produce an output signal representative of the concentration of the target gas independently of other gases in the sample gas. A method of measuring low concentrations of a target gas is also disclosed.
