摘要： Method and apparatus for monitoring hydrocarbon-based fuel properties by measuring the presence and amount of fuel component molecules in the fuel solution. Detection is made of absorption related to signature vibrational modes associated with the fuel component molecules when excited in the mid-IR. In one embodiment, a mid-IR light source illuminates the fuel in-situ and a narrow bandwidth detector associated with a vibrational mode signature detects absorbance as an indication of the presence and quantity of the fuel component in solution. From the determined fuel component quantity and known characteristics, the fuel solution properties are predicted. In one embodiment, octane rating and vapor pressure for a fuel solution is determined in-situ and in real time.

摘要： The present invention provides an apparatus for measuring a property of a sample using low resolution Raman spectroscopy. The apparatus includes a multi-mode laser element, a wavelength dispersion element, a detector, and a processor. The multi-mode laser element irradiates a sample with laser radiation to produce a Raman spectrum. The collection element collects the radiation scattered from the molecules of the sample and transmits the scattered radiation to the dispersion element. The dispersion element disperses the scattered radiation into different wavelength components. The detection array detects the different wavelength components. A processor processes data from the detector array to identify a constituent or to measure a property of the sample. The apparatus preferably has a resolution of between 30 cm.sup.-1 and 50 cm.sup.-1. The resolution of the apparatus being determined in part by the spectral full width at half maximum of the multi-mode laser, and, in part, by the dispersion element.

摘要： Methods for marking a liquid and methods and systems for identifying marked liquids. A liquid can be marked for identification purposes with at least a first marker and a second marker. Each of the markers is miscible with the liquid. The markers are mixed in the liquid so that the ratio of the concentration of the first marker to the concentration of the second marker is substantially equal to a predetermined value. Thus, when a system according to the invention measures the concentrations of the first and second markers, the system can compare the ratio of the measured concentration of the first marker to the measured concentration of the second marker with a look up table of the predetermined values to provide information concerning the identity of the liquid. In a preferred embodiment, the concentration of the markers is measured using an absorption spectrometer. When using an absorption spectrometer to measure the concentration of the markers, each of the markers has an absorbance spectrum with at least one wavelength range where the marker's absorbance is differentiable from the absorbance of the background liquid and any other marker in the liquid.

摘要： Spectroscopic systems and methods are disclosed for determining levels of at least one analyte in blood undergoing hemodialysis. In one aspect, the invention employs Raman spectroscopy to monitor and/or control hemodialysis. In one embodiment, the system uses a laser light directed to circulating blood from a patient undergoing dialysis to make Raman spectral measurements. For example, the laser light can be directed into a segment of the dialysis tubing. The system can utilize unique Raman spectroscopic signature of one or more analytes, e.g., urea, to identify and quantify such analytes against a whole blood background. Based on the spectral response, the concentration of the analytes can be monitored and/or used to control hemodialysis.

摘要： Systems and methods for material analysis are disclosed in which a material (e.g., a food of food ingredient) is illuminated at a plurality of discrete wavelengths. Measurements of the intensity of reflected light at such wavelengths are taken, and a analysis of reflection ratios for various wavelengths is performed. Changes in the reflection ratios are correlated with specific material properties such as the concentration of analytes or the condition of the material (e.g., spoilage, ripeness, degree of cooking or other processing stages).

摘要： The present invention provides low resolution Raman spectroscopic systems and methods for in-vivo detection and analysis of a lesion in a lumen of a subject. The system uses a multi-mode laser attached to a catheter in making in-vivo Raman spectroscopic measurements of the lumen. The system includes a light collector and/or a light dispersion element as well as a detector to measure spectral patterns that indicate the presence of the lesion. Based on the spectral response of the lumen, the presence (or absence) of a lesion can be determined. In addition, the components of the lesion can also be identified based on the unique Raman spectrum associated with each component.
