Abstract
The present invention relates to a computer-implemented method for identifying an incorrectly or non-calibrated infrared spectrometer, comprising the steps of a) recording an infrared spectrum of a sample with a first infrared spectrometer to provide a sample infrared spectrum, b) recording an infrared spectrum of the same sample as in step a) with a second infrared spectrometer to provide a reference infrared spectrum, wherein said second spectrometer is a correctly calibrated infrared spectrometer, or b′) providing a reference spectrum of the same sample as in step a), wherein said reference spectrum was recorded on a second infrared spectrometer, which is a correctly calibrated spectrometer, c) determining a difference between the wavelength of each extreme point in the sample of step a) and the wavelength of each extreme point in the reference spectrum of step b) or b′), and d) indicating the infrared spectrometer of step a) as incorrectly calibrated or non-calibrated, when at least one difference was determined in step c).
