One of the more exciting recent developments in infrared spectroscopy has been the coupling of the spectrometer to an infrared microscope. This development has been so rewarding and so useful in solving today's chemical problems that infrared microspectroscopy has quickly become a significant subclassification of infrared spectros- copy, taking its place beside GC-FTIR, HPLC-FTIR, internal reflec- tion, diffuse reflection, photoacoustic spectroscopy, etc. Infrared microspectroscopy has a much longer history than the recent enthusi- asm would imply, however. The great interest in the use of infrared spectroscopy to solve chemical problems that occurred shortly after World War I1 spread into the medical and biological fields. The combi- nation of the then new infrared spectrometer and a microscope was a natural thought of scientists in these fields. As a result, there are several papers in the literature describing homemade infrared micro- spectrometers. The first such instrument appears to have been built at Oxford in H. W. Thompson's laboratory [1]. Several other literature descriptions followed until in 1953 Coates, Offner, and Siegler of Pe rkin-Elme r Corporation described the first commercial infrared microspectrometer [2] It consisted of an infrared microscope attach- ment, designated the Model 85, for their then current Models 12, 112, and 13 spectrometers. The claimed minimum sample size needed to obtain a satisfactory spectrum with this system was 100 ng. Since spectrometers of that time were sodium chloride prism instruments, whose energy utilization was not high, alignment was always critical and long recording times were necessary. These problems, together with the plethora of chemical research areas which were opened up by the development of infrared spectroscopy, led to an essential loss of interest in infrared microspectroscopy by workers in the field. |
