Measuring Relative Viscosity
in Polyamide Pellets using
AOTF-NIR Spectroscopy
Abstract:
A Brimrose
AOTF-NIR Free
Space
spectrometer was
used to scan
samples of
polyamide
pellets. The
regression model
showed good
results despite
the fact that
only ten samples
were used to
build the
calibration. The
model was
validated by
predicting
unknown samples
for relative
viscosity.
