    Abstract: 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 CO2 (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.

    Abstract: Compensating for frequency drift of a reference energy source in an FT interferometer based spectrometer instrument may include obtaining data representing a reference interferogram collected in response to a trigger signal having been generated in dependence on the emission frequency of the reference energy source, and subsequently obtaining data representing a target interferogram 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 may further include comparing the obtained data to determine a phase shift between the interferograms in a window in at least one region away from center-burst, and generating a mathematical transform dependent on the determined shift to be subsequently applied to generate data representing a frequency stabilized interferogram of an unknown sample recorded by the FT interferometer.

    Abstract: Compensating for amplitude drift in a spectrometer may include making successive performances of a standardization process to generate, at each performance, a mathematical transform to compensate for amplitude drift for application by an arithmetic unit to a spectrum obtained by the spectrometer in an interval between the performances. The compensating may include modifying the mathematical transform with a function dependent on spectral data from a zero material measured in association with the standardization process and the single beam zero spectrum measured in an interval between performances. The compensating may include applying the modified mathematical transform to a spectrum from an unknown sample.
