Abstract
In order to evaluate NMR spectrometer as the analytical tool for identification of individual adjuvant in crop protection products, the standard sample of individual adjuvant was analyzed by NMR spectrometer and then the formulation of crop protection products was also analyzed. Almost polymer system of surfactant was a co-polymer and there was an excess of ethylene. The most intense signal comes from long polyethylene blocks, 70.5 ppm. The carbonyl groups of ester group resonate at 173.5 ppm. Analytical sample was prepared in NMR tube without extraction, cleanup, concentration, or chromatographic separation. Identification of individual adjuvant in crop protection products was conducted by comparison of sample and reference spectra. NMR spectrometer was useful to analyze adjuvant in crop protection products without preparation process.
