This study has been conducted to verify the applicability of FT-NIR (Fourier Transform NearInfrared) to prove coidentity between market agrochemical products and registered prescriptions. Thespectrum correlations were investigated on 83 registered samples and there market products, 23 productswhich had same formulation and active ingredients and 68 products which had different active ingredients. In83 samples/products, the primary differentiated spectrum correlation values were 95.86~100%, which meanthat all samples qualified over 95% threshold. In 23 products which had same active ingredients andformulations, correlation values were 29.09~99.83%. 3 products over 99.0% were proved to have same active/inert ingredients and formulations although they're from different manufacturers. The rest products except the3 items were under 95%. In 68 products had different active ingredients, correlation values varied from2.00% to 93.70%. Higher correlation is supposed to come from similarity of inert ingredients despite differentactive ingredients. They can be decided to unqualify under 95% threshold. So applicability of FT-NIR hasbeen verified on qualitative distinction of coidentity between registered market agrochemicals.Key words agrochemical, FT-NIR, discrimination, feasibility |
