PCA, PCR, PLS: Calibration Methods in NIR Spectroscopy

NIR spectra very rarely have clearly distinguishable peaks that correlate unambiguously with the composition of a sample. However, thanks to chemometric methods such as PCA, PCR and PLS, clear signals can also be extracted in the NIR range.

Avoiding scattering errors in NIR spectroscopy

Scattering effects can significantly complicate the evaluation of NIR spectra. Preprocessing steps such as MSC or SNV help here.
