An instrument has been designed to measure residence time distribution (RTD) in an extruder in a fast semiautomatic fashion. The instrument is composed of a spectrophotometer fiber optically coupled to the exit port of the extruder. Experiments illustrate the effects of screw design and rotation speed on RTD elution profiles.
