Atmospheric-Pressure Thermal Desorption Ionization

Purdue Creates Simpler Alternative For Chemical-Analysis Method. ‘Purdue University researchers have developed a relatively simple alternative to sophisticated techniques now used to ionize materials, a critical step needed for chemical analyses involving instruments called mass spectrometers. Unlike current techniques, the method works at ordinary atmospheric pressure instead of inside a mass spectrometer’s vacuum chamber, and it does not require exotic technologies such as electron beams and lasers, said R. Graham Cooks, the Henry Bohn Hass Distinguished Professor of Analytical Chemistry in Purdue’s College of Science.’
