The Man Behind The Technology Of "CSI"

The system is used for high-throughput screening of foodstuffs for melamine, and related trace analysis experiments, using ionization of whole samples such as milk, biological tissue, or even a suitcase.

From Live Science:

R. Graham Cooks, Purdue University's Henry Bohn Hass Distinguished Professor of Analytical Chemistry, has made mass spectrometry appeal to mass audiences with technology featured on the hit series "CSI." Mass spectrometry turns molecules into ions so their mass can be analyzed, and traditionally requires chemical separations, manipulations of samples and containment in a vacuum chamber.
