This Application Note shows that visible near-infrared spectroscopy (Vis-NIRS) can be used for the quantification of five effective insecticide and herbicide components (Abamectin emulsifiable concentrate (EC), Emamectin EC, Cyhalothrin EC, Cypermethrin and Glyphosate) in pesticides. Vis-NIRS is an excellent alternative to conventional lab methods, saving both cost and time.
