Hemoglobin Detection in Opaque Particular Fluids

A measurement system for free hemoglobin in opaque particular liquids was developed. Sophisticated systems for specific toxin removal in extracorporeal blood purification are based on particular adsorbent suspensions. In case of treatment problems (too high shear forces to erythrocytes) red blood cells are damaged and hemoglobin is released. To protect patients from red blood cell damage, a detection device for fHb is needed. A spectroscopic fHb measurement system was developed and tested based on light reflection/scattering on the particular suspension.
