71 METHOD FOR THE DETECTION OF CELLULAR ABNORMALITIES USING FOURIER TRANSFORM INFRARED SPECTROSCOPY EP96940389.0 1996-11-12 EP0873506A1 1998-10-28 COHENFORD, Menashi, A.; BHANDARE, Prashant S.; CAHN, Frederick; KRISHNAN, Krishnaswamy; RIGAS, Basil
This invention teaches a method to identify cellular abnormalities which are associated with disease states. In one aspect, the invention is a method to distinguish premalignant and malignant stages of cervical cancer from normal cervical cells. The method utilizes infrared (IR) spectra of exfoliated cervical cells which are dried on an infrared transparent matrix and scanned at the frequency range from 3000-950 cm-1. The identification of samples is based on establishing a calibration using a representative set of spectra of normal, dysplastic and malignant specimens. During the calibration process, multivariate techniques such as Principal Component Analysis (PCA) and/or Partial Least Squares (PLS) are used. PCA and PLS reduce the data based on maximum variations between the spectra, and generate clusters in a multidimensional space representing the different populations. The utilization of Mahalinobis distances, or linear regression (e.g., Principle Component Regression on the reduced data from PCA) form the basis for the discrimination. This method is simple to use and achieves statistically reliable distinction between the following groups of cervical smears: normal (individuals with no prior history of dysplasia), dysplasia and malignant samples. Further, this invention discloses a method to obtain the IR spectrum of individual cervical cells fixed on an infrared transparent matrix and to use the spectra of the individual cells in the method described above. In an additional aspect, the invention is a method for using vibrational spectroscopic imaging to distinguish between normal and diseased cells.

73 Method and apparatus for process control using fourier transform infrared spectroscopy US09636560 2000-08-11 US06539285B1 2003-03-25 Wilfried Hartmann; Arno Simon
The invention concerns a method and a device for process control of reaction processes using Fourier transform infrared spectroscopy. In accordance with the invention, an interferogram is generated before or after interaction with the compositions. Subsequent thereto, the interferogram is inspected in segments for externally introduced intensity fluctuations. The intensity fluctuations are subjected to an analysis procedure involving integration, differentiation, or the like, and on the basis of this evaluation, a decision is made as to whether or not the interferogram has an acceptable degree of interfering signals. The interferogram is labeled with this evaluation result and the procedure is repeated a plurality of times. After a sufficient number of acceptable interferograms have been collected, the acceptable interferograms are summed and subjected to a Fourier transform process to extract the frequency dependence. In this manner, Fourier transformation infrared spectroscopy techniques can be applied for process control of processes which would otherwise be impossible due to unacceptably large degrees of interference caused primarily by bubble formation.

An improved open-path fast Fourier infrared spectrometer includes a circuit or algorithm which performs real-time, spectral alignment on measured interferograms to reduce measuremental errors. The improved spectrometer measures selected water vapor lines in a measurement path and compares the centerline of these measured water vapor lines to a reference library. From two or more such comparisons within the spectrometer bandwidth, the spectrometer calculates correction factors for the entire bandwidth. The improved spectrometer performs an overlap and add algorithm which applies the correction factors to perform bandwidth segment-specific shifts on subsequently measured interferograms.

An improved method for use with an open-path fast Fourier infrared spectrometer performs real-time, spectral alignment on measured interferograms to reduce measuremental errors.

79 Continuous flow apparatus and method for interfacing liquid chromatograph and fourier transform infrared spectrometer US434306 1995-05-02 US5538643A 1996-07-23 George J. Kallos; Richard R. Papenfuss
Apparatus for interfacing a liquid chromatograph (LC) with a spectrometer such as a Fourier transform infrared spectrometer, the LC having an eluant, the eluant containing a solvent and a component of interest. The apparatus includes five basic parts. The first is a means for generating a stream of droplets of the eluant, such as a nebulizer. The second is a means for removing most of the solvent from the stream of droplets of the eluant to thereby generate a stream of particles, the particles containing the component of interest and any residual solvent, such as a membrane solvent separator/momentum separator combination. The third is a cryogenic receiving surface, such as a gold drum. The forth is a means for focusing the stream of particles onto the cryogenic receiving surface so that the particles adhere to the cryogenic receiving surface, such as a one and two-tenths millimeter inside diameter stainless steel tube positioned with a gap between the distal end of the tube and the cryogenic receiving surface of one-quarter millimeter. The fifth is a means for controlling the temperature of the cryogenic receiving surface, such as a helium refrigerator. In operation, the cryogenic receiving surface is maintained at a temperature effective to cause the particles to adhere to the cryogenic receiving surface to form a region of adhered particles, such as a temperature of between seventy and one hundred and five degrees Kelvin, the cryogenic receiving surface being maintained in a partial vacuum. Then, the cryogenic receiving surface is warmed, e.g., to between one hundred and five and two hundred degrees Kelvin, to volatilize essentially all of any remaining solvent from the region of adhered particles prior to spectroscopic analysis of the region of adhered particles.
80 Method and apparatus for determining mirror position in a fourier-transform infrared spectrometer US175513 1988-03-31 US4847878A 1989-07-11 Robert R. Badeau
The position of the moving mirror (20) in a Fourier-transform infrared spectrometer is monitored with a circuit which has an incremental counter formed of a plurality of cascaded up/down counters (82, 84, and 86) that count the pulses received by a laser detector (42) to yield a relative position count. A microprocessor (100) maintains an absolute position count by reading the counters (82, 84, and 86) and updating its absolute position count at regular intervals. A portion of the circuit is dedicated to discriminating the direction of the moving mirror (20) by gating circuitry connected to the digitized output of the laser detectors (42, 44).
