Progress in elemental trace analysis means that lower con— centrations can be determined in a more reliable and efficient way. The demands posed to trace element analysis follow generally the tendency that lower and lower concentrations should be determined in matrices which become more and more complex. The most economical scientific strategy depends strongly on the element to be determined, o...
Rice samples were obtained from the Red River region and some other parts of Vietnam as well as from Yanco, Australia. These samples were analysed for 14 elements (P, K, Mg, Ca, Mn, Zn, Fe, Cu, Al, Na, Ni, As, Mo and Cd) by ICP-AES, ICP-MS and FAAS as described in Part 1. This data matrix was then submitted to multivariate data analysis by principal component analysis to investigate the influen...
Elemental analysis is a powerful analytical tool for purity determination. However, it prone to manipulations. Herein, we introduce an approach provide original elemental data, allowing verification of the currently just listed values.
