ELEMENTAL ANALYSIS OF COW’S MILK APPLYING SEM-EDX SPECTROSCOPY TECHNIQUE

Abstract

The present study has been conducted to investigate the microstructure and elemental analysis of cow’s milk by applying scanning electron microscopy (SEM) using energy-dispersive X-ray spectroscopy (EDX) analytical technique. For this task cow’s milk collected from the dairy farm situated in Landhi cattle colony, Karachi. After drying (above 85 oC), sample was exposed under the scanning electron microscope and EDX observations were recorded in four particulates. Results showed that this technique is adequate for qualitative measurement of elements in the milk sample. In contrast, quantitative measurement through EDX was satisfactory for measurement in comparison to other quantitative techniques such as Atomic Absorption Spectroscopy.
