Microwave-assisted UV digestion is a powerful technique for the ultra-trace analysis of liquid samples with a high content of organic compounds, e.g. seawater, effluents, sewage, body fluids or beverages. UV irradiation of dissolved compounds leads to the formation of several highly reactive oxidative species, which accelerate the digestion of interfering substances or enable the determination of total dissolved nitrogen, phosphorus and carbon by converting various N, P, and C containing compounds to nitrate/nitrite, orthophosphate and carbon dioxide.
