Materials Analysis Center

The Materials Analysis Center (MAC) is part of the Georgia Tech Research Institute (GTRI). The lab is located on the second floor of the Baker building and occupies 3,100 square feet of space which is used for chemical and materials processing and analytical/materials testing. The lab is used for a wide variety of government, industry, and academic research programs on a "for fee" basis. The researchers have over 100 years of combined experience in the following specialities: thin-films; corrosion; minerals; electronics reliability/degradation mechanism/contamination; polymers and polymer recycling; magnetic and conductive materials; BRDF determinations; pulp and paper/recycling; ceramics; phosphors; composites, particulates, paints and coatings.

The GTRI Materials Analysis Center has several instruments to facilitate quality materials analysis. A high resolution (2 nm) Field emission Hitachi S4100 Scanning Electron Microscope, with Noran thin window light element X-ray Spectrometer is available and is equipped with back-scatter electron detector, quantitative software, and full-color display. A high resolution (2 nm) field emission Hitachi S4100 scanning electron microscope equipped with a NORAN thin window light element x-ray detector, image analysis (compositional mapping and line scans) and quantitative software, and full color display is available. The Hitachi SEM also contains a TV speed four quadrant backscatter detector (operable at 500 volts) and houses a custom built conductivity probe. An Acton MS-64 Microprobe with two XX-ray wavelength spectrometers, a Rigaku D/Max-11B Microprocessor Controlled Automated X-Ray Powder Diffraction System, and a Mattson Sirus 100 FTIR Spectrometer (Range 0.35 to 20 ┬Ám) are also available. The center also has facilities for thermal analysis and includes a Seiko Instruments Simultaneous TG/DTA 320 and a DuPont 9900 DSC, TMS, DMA. A seiko TG/DTA Gas Transfer system for evolved gas analysis by FT-IR is also available. A customized instrument has also been built for measuring bi-directional reflectance distribution functions (BRDF) of materials in the visible spectral region.

The MAC laboratories also include a variety of optical microscopes, two Lietz metallographs, Wilson Hardness and Microhardness testers, a Denton DV-502 vacuum evaporation chamber, a Hummer VI Sputter Coater, Reichart and Sorval microtomes, Laminar flow and regular hoods, a Struers Tenupol electrolytic jet-thinning device, a Gatan ion mill (with cold-stage), dark-room and printing facilities, polishing abd wood shop facilities, and numerous other support equipment and specialized attachments.
