Preprocessing NIR Spectra for Aquaphotomics

Autor: Jean-Michel Roger, Alexandre Mallet, Federico Marini

Publikováno v: Molecules, Vol 27, Iss 20, p 6795 (2022)

Even though NIR spectroscopy is based on the Beer–Lambert law, which clearly relates the concentration of the absorbing elements with the absorbance, the measured spectra are subject to spurious signals, such as additive and multiplicative effects.

Fast and robust NIRS-based characterization of raw organic waste: Using non-linear methods to handle water effects

Autor: Alexandre Mallet, Cyrille Charnier, Éric Latrille, Ryad Bendoula, Jean-Michel Roger, Jean-Philippe Steyer

Publikováno v: Water Research. 227:119308

Fast characterization of organic waste using near infrared spectroscopy (NIRS) has been successfully developed in the last decade. However, up to now, an on-site use of this technology has been hindered by necessary sample preparation steps (freeze-d
