An infrared investigation in relation with chitin and chitosan characterization
Open accessAbstract
Abstract The use of infrared spectroscopy for characterization of the composition of chitin and chitosan covering the entire range of degree of acetylation (DA) and a wide variety of raw materials is examined further. The ratio of absorbance bands selected was calibrated using 1 H liquid and 13 C CP-MAS solid-state NMR as absolute techniques. IR spectra of the structural units of these polymers validated the choice of baselines and characteristic bands. The bands at 1650 and 1320 cm −1 were chosen to measure the DA. As internal reference, the intensities at 3450 and 1420 cm −1 were evaluated. The absorption band ratios involving the reference at 3450 cm −1 had poorer fit.. The absorption ratio A 1320 / A 1420 shows superior agreement between the absolute and estimated DA-values (DA%=31.92 A 1320 / A 1420 −12.20; r =0.990).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
