Projeto NIRS ID

Hi @LatinXChem, this is our work ‘Correction of the moisture variation in wood NIR spectra for species identification using EPO and soft PLS2-DA’. We hope you all like it as much as we enjoyed doing it! For more information, please follow the thread #LatinXChem #LXChemAna #Ana23

@AlmaRevilla5 @LatinXChem And we simply sand the sample with 80 grit sandpaper. Such granulation allows a greater contact surface between the wood and incident IR radiation, maintains granulometric uniformity, removes the oxidized outer surface layer, and prevents the formation of specular highlights

@AlmaRevilla5 @LatinXChem Hi Alma! Thank you ☺️ Wood is essentially composed of cellulose, hemicelluloses, lignin, and extractives. Wood species will have a different amount of each compound and types of extractives. The NIR spectra will reflect that

@MYCombariza @LatinXChem If you have any other questions, please let me know 😊

@MYCombariza @LatinXChem It has been proven effective not only to identify similar species but also to determine the provenance within the same species. Despite that, we use a portable device that allows in-field analysis, such as sample inspection posts.

@RhayzaOliveiraa @LatinXChem Thank you! We appreciate it 😊

@nirs_ID @LatinXChem Congratulations, great job!

We will be glad to answer any questions or provide any additional details as you need. Thank you! #LatinXChem #LXChemAna @LatinXChem #Ana23

Thus, EPO and soft-PLS-DA proved to be an effective strategy to enable the application of NIR technology in field conditions for wood species identification #LatinXChem #LXChemAna @LatinXChem #Ana23
