The 38 transition metals have a distinguishing characteristic—valence electrons present in more than one shell that combine with other elements. Transition metals often exhibit several common oxidation states. When used or disposed of incorrectly, they can contaminate soil or water. Several studies have linked specific transition metals to various diseases.
Traditional methods for transition metal detection can have limited sensitivity and solute vaporization interferences. Ion chromatography is ideal for separating transition metals, with the ability optimize or alter separation simply changing eluents.
Various regulatory agencies have set guidelines for quantities of transition metal elements in food, water, and pharmaceutical products. See below for some examples.
