摘要
A method for improving the sensitivity of measurements in Infrared Spectrometer Fourier Transform path open conducting a number shift correction signal in the spectrum of the elements to be analyzed within a bandwidth of the spectrometer the method comprising the steps of: a) selecting a plurality of known components within a defined spectral region; b) measuring the wavelength of each of the plurality of selected components; c) determining a wave number shift for each of the plurality of measured components by comparing the measured values the reference values; d) determining a statistical center of the plurality of wave number shifts determined in step c; e) generating a correction line shift wavenumber through the statistical center of step d) and delorigen defined by a wavenumber 0 by a correction 0; and f) correcting subsequent spectrometer measurements by shifting the measured wavelength along line offset correction number determined in step e wave).
