Above, schematic drawing of the principle of the CHX-determination (right) measuring the reduced fluorescence of the polysterene plates due to absorbance of the excitation light by the CHX in the solution (left). Below, intensity (relative fluorescence units, RFU) of emission wavelengths (nm) determining a solution without (no CHX) and with 0.01% CHX in the polysterene plates excited with 280 nm. Additionally, the relations between the fluorescence intensity measured for the solution without and with 0.01% CHX are presented
