On the use of deep UV-LEDs for monitoring dialysis

The new UV-C LEDs have been characterized to evaluate their potential applicability in the development of a simple, low-cost optical adequacy sensor for continuous, on-line measurements on spent dialysate. This approach would allow us to avoid the use of bulky and expensive spectrometers in the monitor systems. The reported results could be useful for the system development; nevertheless, different critical aspects such as LEDs reliability, mean life time and emitted and transmitted power-monitoring should be taken in consideration.
