A new, high-speed, automated instrument for measuring foreign matter including microdust and trash in bale or processed fiber is described. The method uses aero- mechanical release and separation and electro-optical sensing for microdust, trash, and lint. Data are provided proving the correlation of an experimental prototype gin monitor's readings with readings of other methods. Example data for both microdust and trash are given for both gin and textile mill cleaning machinery performance.
