Abstract
An infrared spectroscopy instrument includes a housing having a sample chamber which is sized and shaped to accommodate the body of an automatic feeding slide projector of the type commonly utilized with standard photographic slide transparencies. The infrared beam is reflected by a system of mirrors into a beam path which extends through a portion of the slide projector mechanism ordinarily occupied by the projector lamp and optics, which have been removed. Samples are held in special sample holders adapted in size and shape to fit the compartments utilized in the slide magazine of the projector. These sample holders are indexed one at a time under the control of the instrument into a viewing position in the path of the infrared beam, and the beam passed through the sample is then collected and focused onto a detector. The feeding apparatus of the projector allows any selected sample holder in the magazine to be indexed into the slide viewing position, and allows automatic computer control of the order in which the samples are analyzed.
