Testing of deposit control chemicals for broke in laboratory The principle in testing of deposit control chemicals on a laboratory scale is to compare the responses of different chemicals to the selected property. In a fixing test, the turbidity of a pulp sample is measured as a function of chemical dosing. In aqueous phase the
