Thünen: New publication: Determination of terpenes using Near Infrared Spectroscopy

Institute of

HF Wood Research

The study analyzed terpene emissions from Pinus sylvestris using NIR and compared them with the EN 16516 method. Prediction models for α-pinene and 3-carene showed good results.

[Translate to English:]

The Human Health and Consumer Protection working group of the Thuenen Institute of Wood Research, worked on a new method for determining terpene emissions from wood.

The innovative approach utilized near-infrared spectroscopy (NIR) in combination with statistical models to measure terpene emissions more quickly and efficiently. A clear correlation was found between the NIR spectra and the emissions of α-pinene and 3-carene. Prediction models demonstrated high accuracy, with a determination coefficient of 0.77 and a deviation of only 12%. This method could be used in the future to identify woods with high emissions at an early stage and better control emissions – with significant time savings compared to the standard measurement method.
