Abstract The spectra of sulfamethoxazole, the efficient ingredient of sulfanilamide-like medicine, were investigated by combining the TLC and FT-Raman spectroscopy using the surface enhanced Raman spectroscopy technique. The result indicates that the main vibrant characteristic spectral band can be obtained by TLC in a samples of just about 1 μg. The difference between the compound sulfamethoxazole and the corresponding spectra picture is analyzed. The analysis shows that the method of combining TLC and FT-Raman spectroscopy by the SERS is practical and advantageous in the highly sensitive measurement of the chemical ingredient in medicine.
