Fluorescence quenching

 

The “quenching” of the fluorescence in the paper machine circuit may be necessary during grade changes between grades with different whiteness degrees, or between whitened and non-whitened grades.

 

QUENCHOPHOR® E 1449

offers a high fluorescence quenching.

 

QUENCHOPHOR® 35

is working very well at moderate dosages to reduce the fluorescence to a certain level.
