Model-based pre-processing in Raman spectroscopy of biological samples
Liland, Kristian Hovde; Kohler, Achim; Afseth, Nils Kristian (Peer reviewed; Journal article, 2016)Model-based pre-processing has become wide spread in spectroscopy and is the standard procedure in Fourier-transform infrared spectroscopy. It has also been shown to give valuable contributions in Raman spectroscopy. ... -

Monitoring Secondary Structural Changes in Salted and Smoked Salmon Muscle Myofiber Proteins by FT-IR Microspectroscopy
Carton, Izaskun; Böcker, Ulrike; Ofstad, Ragni; Sørheim, Oddvin; Kohler, Achim (Peer reviewed; Journal article, 2009)Fourier transform infrared (FT-IR) microspectroscopy and light microscopy were used to study changes in the myofibrillar proteins and microstructure in salmon muscle due to dry salting and smoking. Light microscopy showed ... -
Optimizing Savitzky-Golay Parameters for Improving Spectral Resolution and Quantification in Infrared Spectroscopy
Zimmermann, Boris; Kohler, Achim (Peer reviewed; Journal article, 2013)Calculating derivatives of spectral data by the Savitzky–Golay (SG)numerical algorithm is often used as a preliminary preprocessing step to resolve overlapping signals, enhance signal properties, and suppress unwanted ... -
Preprocessing Strategies for Sparse Infrared Spectroscopy: A Case Study on Cartilage Diagnostics
Tafintseva, Valeria; Lintvedt, Tiril Aurora; Solheim, Johanne Heitmann; Zimmermann, Boris; Rehman, Hafeez Ur; Virtanen, Vesa; Shaikh, Rubina; Nippolainen, Ervin; Afara, Isaac; Saarakkala, Simo; Rieppo, Lassi; Krebs, Patrick; Fomina, Polina; Mizaikoff, Boris; Kohler, Achim (Journal article; Peer reviewed, 2022)The aim of the study was to optimize preprocessing of sparse infrared spectral data. The sparse data were obtained by reducing broadband Fourier transform infrared attenuated total reflectance spectra of bovine and human ... -

The aim of the present study was to ... -
The relationship between fatty acid profiles in milk identified by Fourier transform infrared spectroscopy and onset of luteal activity in Norwegian dairy cattle
Martin, Adam Dunstan; Afseth, Nils Kristian; Kohler, Achim; Randby, Åshild Taksdal; Eknæs, Margrete; Waldmann, Andres; Dørum, Guro; Måge, Ingrid; Reksen, Olav (Peer reviewed; Journal article, 2015)To investigate the feasibility of milk fatty acids as predictors of onset of luteal activity (OLA), 87 lactations taken from 73 healthy Norwegian Red cattle were surveyed over 2 winter housing seasons. The feasibility of ... -
