Spectral response of lignin and soluble phenolics in the near infrared measured with different methods and spectrometers - a comparative study.

Abstract

Solid evidence that the spectral signatures of lignin and soluble phenolics are very similar and wavelengths used fomerly for lignin determination are in fact likely to be due to tannin and lignin reflectance features.
