Abstract
In an instrument for optically analyzing particulate samples such as grain samples, the sample is introduced into a chute which is received in a vibrating apparatus to vibrate the grain in the chute and compact it. The chute is then dropped to a carriage which transports the chute and the grain through a beam of narrow band infrared light. A photocell is positioned to detect the amount of light passing through the grain sample.
