Abstract:
Methods and systems for monitoring and/or controlling protein separation, purification, extraction, and/or fractionation processes are provided. The impedance of a protein mixture undergoing a protein process is measured and compared to a target reference impedance value or range of reference impedance values. If the measured impedance is not within an acceptable deviation of the target reference impedance value, a parameter of the protein mixture or process is adjusted.
