Overhead Projector Demonstrations
Mass Spectrometry Analogy on the Overhead Projector
Nancy C. Grim and Jerry L. Sarquis
Miami University, Oxford, OH 45056

October 1995
Vol. 72 No. 10
p. 930
Abstract
An analogy for the principle of separation by mass spectrometry has been developed that uses the overhead projector. Metal spheres are rolled down an inclined Plexiglas sheet which has a magnet underneath. The spheres are deflected as they roll down the incline. The degree of deflection is inversely related to the mass of each sphere.
