Abstract
A method of determining a residence time distribution comprises mixing a molding batch (104) and a tracer (105), wherein the tracer has a ferroelectric curie temperature above 120° C., and transmitting the mixture through a capacitor (107). Further, the method comprises measuring a capacitance of the capacitor, and determining a residence time distribution based on the measured capacitance. In particular, the ferroelectric curie temperature of the tracer may be above 150° C. and preferably the ferroelectric curie temperature of the tracer is above 200° C.
