A method to accurately determine and quantify manganese, molybdenum and zinc using Optical Emission Spectroscopy-Inductively Coupled Plasma by optical emission spectrometer was optimized and validated. Selectivity/specificity, linearity, repeatability, intermediate precision and bias using reference materials and certified matrix reference material, respectively, were determined.
