Construction and analytical application of an on-column photo reactor for improved detection of iron-species as plant metabolites in capillary flow injection and capillary electrophoresis.

An on-column photo reactor for CE, which is constructed from UV-transparent capillaries and a small Pen-Ray UV lamp, is applied to the analysis of small, non-covalent iron-species. These iron-species, e.g. phytosiderophores (PS) in grasses and the non-protein amino acid nicotianamine (NA), play an important role in plant metabolism. The photo reactor is… CONTINUE READING
