The Determination of Low
Level Moisture in Methyl Alcohol
Using AOTF-NIR Spectroscopy
Abstract:
A Brimrose AOTF-NIR
spectrometer was used to
scan spectral data on
prepared samples of methanol
with small amounts of water
added. The reference data on
water in the methanol and
the corresponding spectral
data were used to create a
regression model that
clearly showed that the
Brimrose AOTF-NIR
spectrometer is able to
quantify small amounts of
water in methanol using
spectral data and a
calibration model. Past
experience has shown that a
calibration model generated
from laboratory data can
easily be transferred to a
real-time, on-line
industrial setting.
