摘要： A method for monitoring air quality is described. The method includes measuring ethane and methane using a mobile sensor platform to provide sensor data. The sensor data includes methane data and ethane data captured at a nonzero mobile sensor platform speed. Methane and ethane peak(s) are identified in the sensor data. Correlation(s) between the methane and ethane peak(s) and/or between the methane peak(s) and at least one amount of 13C are determined. A source for the methane is determined based on the correlation.

摘要： The present invention concerns a method for determining at least one absorption band in a spectrum, the method at least comprising the steps of:—providing a measured absorption spectrum from the sample,—providing a calculation spectrum,—from the calculation spectrum, extracting at least one absorption band,—calculating a residual spectrum by removing each extracted absorption band from the calculation spectrum, testing whether a predefined stop criterion is fulfilled by the residual spectrum,—if the stop criterion is not fulfilled, using the residual spectrum as the calculation spectrum and iterating the extracting step, the forming step, the calculating step and the testing step, and—if the stop criterion is fulfilled, outputting each extracted absorption band.

摘要： A method for detecting and quantifying fibrosis, which involves at least; positioning a non-coloured fixed tissue sample on a support; carrying out infrared acquisition, by scanning, of points of the sample; converting the infrared spectrum produced by each acquired point into at least one spectral image; carrying out a digital processing operation on the spectral image by distinguishing between at least physiological collagen and pathological collagen from fibrosis, attributing, to each point, a spectral class defined by an algorithm classifying the spectra according to the spectral similarities % thereof, then attributing a status to each class by statistically comparing with a digital model of spectra; quantifying the relative surface area occupied by the points of each status; and recording the result.

摘要： A preparation method for preparing spectrometric determinations of a measurand in a target application using a spectrometer is provided. On the basis of reference data recorded in the target application, a normalized measurand master spectrum with a spectral distribution characteristic of the measurand is determined. On the basis of the measurand master spectrum, synthetic spectra are generated which cover a value range greater than or equal to a value range covered by the reference values. On the basis of the synthetic spectra, information for carrying out the spectrometric determinations, including information comprising a property, a wavelength range, and/or a path length range for an optical path length suitable for carrying out the spectrometric determinations, and/or comprising a calculation rule, with which, on the basis of measurement spectra in the target application, measured values of the measurand are determined.
