The present application provides a kind of method for automatically controlling ore pulp PH with lime milk of grid residue, belong to the technical field of automatically controlling ore pulp PH with lime milk of grid residue, the present application is calculated by online densimeter and ore pulp temperature sensor effective alkali concentration of lime milk and feedforward correction flow setting value, utilize redundant double pH electrode and kalman filter fusion estimation ore pulp pH value, based on mechanism titration curve model driving gain scheduling controller in different pH work interval automatic switching proportional band parameter, and the cumulative concentration prediction value of ore pulp output by physical constraint digestion kinetics modeling network is fed back to gain scheduling controller correction dosing output, solve the technical problem that lime milk of grid residue delayed release alkali leads to ore pulp pH control system cannot predict potential alkali amount, cause systematic over-alkaline.

Systems and methods are provided for performing a titration analysis to indicate a concentration of a protein present in an experimental sample. The titration analysis system includes a titration analysis instrument having a light source, a thermally controlled sample receiver, and a light detector configured to detect light from the light source after the light has passed through the thermally controlled sample receiver. A non-transitory memory stores a reusable titration curve, and processing circuitry is configured to receive a signal from the light detector, determine a fluorescence polarization value based on the signal, retrieve the reusable titration curve from the non-transitory memory as a reference curve, and fit the fluorescence polarization value to the reusable titration curve to indicate the concentration of the protein present in the experimental sample.
