Multicomponent Quantitative Analytical Method And Apparatus
US Patent:
4660151, Apr 21, 1987
Filed:
Sep 19, 1983
Appl. No.:
6/533833
Inventors:
Russell A. Chipman - Tucson AZ
Robert J. Obremski - Yorba Linda CA

Assignee:
Beckman Instruments, Inc. - Fullerton CA
International Classification:
G06F 15347, G01J 312, G01N 2125
US Classification:
364498
Abstract:
A multicomponent quantitative analytical method and apparatus wherein the method includes the steps of and the apparatus is capable of performing steps of obtaining a plurality of calibration spectra, transforming the calibration spectra using a transform with orthogonal basis vectors, obtaining a calibration matrix relating the transform spectra to concentrations of analytes in the calibration samples, obtaining a spectrum for an unknown sample, transforming the unknown sample spectrum, and relating the transformed unknown sample spectrum to the calibration matrix to thereby determine the concentration of analytes in the unknown sample.
Fiber Optic Sensor For Petroleum
US Patent:
6184980, Feb 6, 2001
Filed:
Feb 27, 1995
Appl. No.:

International Classification:
G01J 300
US Classification:
356300
Abstract:
A silver halide fiber optic for the detection and identification of petroleum. The fiber optic serves both as a waveguide for transmitting a signal to and from petroleum in remote locations and also as an intrinsic part of the sensing element to obtain evanescent wave spectra. The evanescent wave is attenuated at various wavelengths based on the chemical composition of the petroleum in which the sensor is immersed. The spectrum obtained from an unknown sample is compared with the spectrum of known samples from a library to identify the unknown sample.
