摘要： A method of compensating for frequency drift of a reference energy source in an FT interferometer based spectrometer instrument having an arithmetic unit into which has been obtained data representing a reference interferogram (40) collected in response to a trigger signal having been generated in dependence on the emission frequency of the reference energy source and data representing a target interferogram (42) recorded by the FT interferometer in response to a trigger signal also having been generated in dependence on the emission frequency of the reference energy source in the same manner. The method further comprises the comparing in the arithmetic unit the data representing the reference interferogram (40) and the data representing the target interferogram (42) to determining a phase shift (d) between the interferograms in a window W in at least one region (36) away from center-burst (44) and generating in the arithmetic unit a mathematical transform dependent on the determined shift or shifts (d) to be subsequently applied to control the operation of the spectrometer instrument in order to generate data representing a frequency stabilized interferogram of an unknown sample recorded by the FT interferometer.

摘要： A method of quantitative determining the content or concentration of a component in a fluid sample by IR analysis, the method comprising the following steps: a) directing one or more IR light beams through each of a number, n, of different parts of a fluid sample, the IR light including at least one wavelength within a waveband which the component absorbs, b) for each of the n parts of the sample, detecting the IR light having passed through the respective part of the sample, c) obtaining, for each of the parts, at least one value on the basis of the detected IR light, the value representing information from which the content or concentration may be estimated, d) calculating at least two statistical parameters, such as statistical moments, eg. a mean value and a standard deviation, characteristic of a statistical distribution of the obtained values, and e) estimating or determining the content or concentration of the component on the basis of the at least two statistical parameters. Thereby the content may be determined fairly accurate even through the instrument is simple and the measured sample is not homogenised. The obtained accuracy depends on the number of repetitive measurements on each sample. A better accuracy may be obtained by increasing the number of measurements.

摘要： The invention provides a method for standardising an infrared spectrometer based on spectral patterns of constituents of atmospheric air naturally occurring in the spectrometer. The invention also provides a spectrometer applying the method. The method selects a spectral pattern in a recorded spectrum and determines a wavelength dependent position value for a feature, such as the centre of the pattern. This value is compared to a reference value that may be obtained from a spectrum recorded by a master instrument, and a standardisation formula can be determined. The absorption peaks from CO 2 ( g )around 2350 cm -1 are preferred as the selected pattern. The method renders the use of reference samples unnecessary and allows for the standardisation to be performed simultaneously with the recording of a spectrum of a sample of interest.
