07/01-- Hartmut Hedderich, director of Purdue's laser facility, uses Purdue's new portable Raman imaging instrument, or PRIM, to analyze the chemical makeup of a medicine sample. By pointing the laser "gun" at the sample, the laser light creates molecular vibrations in the molecules of Tylenol. The resulting color spectrum, which serves as a "fingerprint" of the chemicals, is shown on the computer screen. (Purdue News Service Photo by David Umberger.)
