CLASSIFICATION OF CALCIUM SUPPLEMENTS THROUGH APPLICATION OF PRINCIPAL COMPONENT ANALYSIS: A STUDY BY INAA AND AAS
Abstract
Different types of Ca supplements are available in the local markets of Pakistan. It is sometimes difficult to classify these with respect to their composition. In the present work principal component analysis (PCA) technique was applied to classify different Ca supplements on the basis of their elemental data obtained using instrumental neutron activation analysis (INAA) and atomic absorption spectrometry (AAS) techniques. The graphical representation of principal component analysis (PCA) scores utilizing intricate analytical data successfully generated four different types of Ca supplements with compatible samples grouped together. These included Ca supplements with CaCO3 as Ca source along with vitamin C, the supplements with CaCO3 as Ca source along with vitamin D, Supplements with Ca from bone meal and supplements with chelated calcium.References
