SpectroScience is the near-infrared spectroscopy course I wished I had when I was learning it the hard way: 32 lessons covering calibration, chemometrics and real-world applications, written in plain words.
The lessons are narrated and illustrated, and they are being rebuilt as animated stories so a method you can see is a method you remember.
It costs a fraction of vendor training, and the companion tools on Spectra Lab let you try each idea on data.
