Abstract

Partial Least Square PLS and Artificial Neural Network ANN techniques were compared during development of an analytical method for quantitative determination of sulfamethoxazole SMX and trimethoprim TMP in Co-Trimoxazole

suspension. The procedure was based on Attenuated Total Reflectance Fourier Transform Infrared ATR–FTIR spectrometry. The 800–2500 cm

spectral region was selected for quantitative analysis. R

and relative error of prediction REP in PLS technique were 0.989, 2.128 and 0.986, 1.381 for SMX and TMP, respectively. These statistical parameters were improved using the ANN models considering the complexity of the sample and the speediness and simplicity of the method. R

and RMSEC in modified method were 0.997, 1.064 and 0.997, 0.634 for SMX and TMP, respectively.
