Infrared Microspectroscopy

Synchrotron radiation based infrared microspectroscopy (SR-IMS) beamline provide considerable brightness advantages over conventional IR sources. The combination of IMS with high brightness synchrotron radiation has greatly improved the spatial resolution of this technique by allowing high quality spectra to be collected from samples whole size is approaching the diffraction limit for this wavelength of infrared.
The end-station of SR-IMS has been open since September 2005. SR-IMS is a technology of combination of the state-of-the-art FT-IR spectroscopy, optical microscope with all-reflecting optics, and synchrotron infrared radiation generated from bending magnet edges in an electron storage ring. The three disciplines have special traits, each adding value of IMS analyses. IMS is a refined technology for the identification and quantification of materials on a microscopic scale. As the shapes and forms of natural objects provided the foundation for biological science, spectroscopy has anchored our understanding of molecular structure. Microscopic examination reveals the fine details of tissue morphology. With inventive skill and imagination, biological found ways to selectively stain tissue, visually defining chemical classes by specific colors. A stained tissue section is a vivid and detailed image of chemical distribution. Now, IMS allows biologists to explore the complex chemistry of biological tissue directly and to relate molecular chemistry with morphology. These analyses may probe composition at a single point or generation an extended map. If spectra from an array of points are collected, then these data can be used to prepare spectral images.
