Abstract
We have shown that Raman spectroscopy can be used to determine the fre e melamine content in melamine-formaldehyde (MF) resins. In contrast t o the conventional liquid chromatography method, the Raman spectroscop ic method can be directly applied to cured resins without sample prepa ration. The necessary assignments of bands were supported by theoretic al analysis of Raman frequencies. In addition, Raman imaging was used to determine the homogeneity of the free melamine content in cured MF resins.
