MRC - Detection System

The detection system comprises a stabilized light source and a sensitive, calibrated photodiode. It enables the user-friendly measurement of light transmitted through a dyed fluid or other transparent materials. As an example the degradation of methylene blue during photocatalysis can be observed in accordance with the German standard DIN 52980 "Photocatalytic activity of surfaces - Determination of photocatalytic activity by degradation of methylene blue". A laser diode with a wavelength of 664nm can be used that matches the absorption peak of the dye.
