Embodiment Construction
[0021] Fourier transform infrared (FT-IR) spectroscopy uses energy in the form of infrared (IR) radiation, which lies between the visible and microwave regions of the electromagnetic spectrum. figure 1 is a schematic diagram of the optics of an FT-IR spectrometer 1, for example for obtaining an IR spectrum of the combined effluent of an acrylonitrile reactor in accordance with the present invention. In one embodiment, figure 1 The FT-IR spectrometer shown schematically illustrates a BOMEM Michelson FT-IR spectrometer incorporating a Michelson interferometer. In the FT-IR spectrometer, a sample to be analyzed is placed in or passed through an FT-IR sample cell 2, which is specially designed to transmit light at infrared wavelengths. IR radiation emitted by a broad-spectrum infrared source passes through the sample cell 2 and travels to a sensitive IR detector 4 . The IR radiation emitted from the light source 3 is split by the interferometer 5 so that the IR radiation follows...
