Inert Atmosphere KBr Pellet Press and Cell Infrared spectra of solids which are sensitive to constituents of the ambient atmosphere (usually oxygen andlor water) are often difficult, if not impossible, to measure using usual pressed pellet equipment, which exposes the sample to the ambient atmosphere during andlor after preparation of the pellet. Several workers have recommended techniqueswhich delay, but do nut prevent, reaction of the sample disk with the atm
