Table 1 Frequencies of different methods reported in the literature for measuring the crystallinity index of commercial celluloses.

From: Cellulose crystallinity index: measurement techniques and their impact on interpreting cellulase performance

Instrument Analysis technique Frequency, %
XRD Peak height 70 to 85
  Peak deconvolution 5 to 10
  Amorphous subtraction 5 to 10
NMR C4 peak separation 5 to 10
  1. NMR, nuclear magnetic resonance; XRD, X-ray diffraction.
  2. About 80 articles (30 for Avicel PH-101 and 50 for other commercial celluloses) were analyzed in this study.
