Reflectance FT-IR has been shown to be a promising technique for rapid
(less than or equal to 2 seconds) quantitative determinations of the
antisapstain chemical didecyldimethylammonium chloride (DDAC) on wood
surfaces treated at 0 to 88 mu g/cm(2). Partial least-squares analysis
allowed selection of a region of the infrared spectra which could be
used for quantitative analyses of DDAC on the wood. The results obtain
ed through this method were comparable to results obtained on the same
samples by HPLC and pyrolysis-gas chromatography/mass spectroscopy. T
his outcome demonstrates the opportunity for applying this FT-IR techn
ique in an industrial setting.
