drift and pas ft-ir techniques have been applied to quantitative analysis of coupling agent, n-2-aminoethyl-3-aminopropyltriethoxysilane ( gamma -aaps) on the e-glass mats. it is shown that both techniques are sensitive to the surface treatment and can successfully be used to quantitatively analyze the surface species. this quantitative approach is shown by a relationship between intensities of the c-h stretching mode as well as the band originating from the e-glass (1638 cm/sup -1/) to the concentration of the coupling agent in the aqueous solution although similar relationships are found for the pas and drift data, the slopes and breakpoints of each calibration curve appear to be different
