Quantitative evaluation by attenuated total reflectance infrared (ATR-FTIR) spectroscopy of the chemical composition of decayed wood preserved in waterlogged conditions

Measuring the chemical composition of waterlogged decayed wood by near infrared spectroscopy

“…This confirms similar occurrences already found with other techniques that in archaeological hardwoods predictions are better than in softwoods when they are processed by multivariate analysis based on spectroscopic techniques [15].…”

“…Spectroscopic techniques in the mid-IR region have been already used for quantitative evaluations of chemical components in decayed wood [9,15]. However, compared to mid-IR, NIR coupled with multivariate statistical analysis (such as partial least squared regression) has some advantages: bulk samples can be directly measured (thanks to low absorption coefficients), hydroxyl groups are better separated in the NIR region than in the mid-IR [16], and, more in general, the predic-data set [17].…”

Application of FTIR spectroscopy to the characterization of archeological wood

“…PC1 and PC2 confirm the negative relationship between lignin and carbohydrate in lignocellulosic biomass(Pandey and Pitman 2003, Bertaud and Holmbom 2004, Sills and Gossett 2012, Pizzo et al 2015.…”

Aging of wood under long-term storage in a salt environment

“…The decrease of this band can also be assigned to deacetylation processes (Mohebby 2008;Stefke et al 2008). Pizzo et al (2015) also found a decrease of the bands at 1730 and 1230 cm -1 when they assessed waterlogged wood samples by ATR-FTIR spectroscopy. Stich (2006) compared recent and waterlogged wood of Pinus sylvestris.…”
