This highly sensitive colorimetric measuring method detects even the smallest concentrations of substances. In conjunction with the use of highly sensitive substances and an optical illusion (double irradiation), there is in an increase in their sensitivity by a factor of between 10 and 100 when compared to other VISOCOLOR® test kits.
Method according to the chemical basis of the German standard methods for testing water, waste water and sludge (DEV).
