Photometric UV -sensor for real -time monitoring of toxins removed by dialysis process in dialysis dialysis dialysis dialysis

摘要

The detector arrangement has an optical cuvette (3) with a wall having a portion transparent for UV radiations, and two UV LEDs (2a, 2b) fixed adjacent to the portion of the wall for emitting the UV radiations with different emission wavelengths in a range of 180-380nm. A wide-band UV photo detector (4) is sensitive for the emission wavelengths of the UV LEDs, and narrow-band UV photo detectors are sensitive for one of the emission wavelengths of the UV LEDs, where the wide-band and narrow-band photo detectors are arranged adjacent to another portion of the wall. An independent claim is also included for a photometric UV sensor comprising planar-convex lenses.
