Transition Metal Analysis

Limitations in colorimetric and atomic absorption spectrophotometric measures have prompted development of alternative methods of transition metal analysis. One example is the use of ion exchange chromatography to assess transition metals in serum and whole blood, a method developed by the company Dionex. While identification of transition metal complexes can also be made on the basis of symmetry (Laporte mle) or spin selection rule or analysis of charge transfer spectra, one of the most significant methods is on the basis of magnetism. The... 

A growing number of applications using post-column derivatization in combination with photometric detection opened the field of heavy and transition metal analysis for ion chromatography, thus providing a powerful extension to conventional atomic spectroscopy methods.

In contrast, transition metal analysis in wine is not a trivial matter. Metals such as aluminum, cobalt, iron, or nickel impact the taste of wine and lead to unwanted clouding [334], and health organizations impose strict thresholds for toxic elements such as lead, cadmium, copper, and zinc. Thus, there is a great demand for a fest, simple, and sensitive multielement method for determining transition metals in wine. In the wine matrix, some of the metals are complexed. Therefore, the organic matrk has to be eliminated. Widely distributed sample...
