Author Message   Annick De Coster (Adc) Posted on Monday, March 08, 2004 - 3:37 am:    Can anyone tell me which wavelengths can be related to lignine content in general or in natural fibres (flax) in special. Detection of lignin content after different corrections (MSC, norris, ...) can also be usefull   NIRman Posted on Thursday, March 11, 2004 - 6:45 pm:    Hello Annick De Coster, Several years ago I co-authored a paper on lignin analysis in wood, comparing results from NIR and FT/NIR. Send me your e-mail address, and I'll send you the details.

The PTS (München) hast developed a method for lignin in paper. regards, Christian   Alessandra Foresti Caldeira Posted on Thursday, April 14, 2005 - 9:36 am:    Dear Don Burns, I read your message to Annick and I would like to know the reference of your paper about the difereces between NIR/FT-NIR. Thank you in advance, Alessandra Foresti Caldeira   NIRman Posted on Thursday, April 14, 2005 - 10:07 am:    Hello Alessandra, This subject was addressed in Chapter 21 "FT/IR Versus NIR -- A Study with Lignocellulose" in the "Handbook of Near-Infrared Analysis" (2nd edition, published by Marcel Dekker in 2001). Four wavelengths were used: 2262, 1828, 2010, and 2430 nm. The paper was also published in Tappi Journal, 73, 209 (1990). Don Burns
