PDF-Metals Analysis

3 IsotopePrincipal interfering species polyatomic ions each of which will have differentreactivity with any given reactive cell gas However every interference shown in Table 1 is a polyatomic ion. This instability is what drives the process of corrosion and it results from the fact that a refined metal is continually trying to revert to its natural state the mineral Some metals do this faster than others The Galvanic Series ranks corrosion te Chapter 4.
