Polymer and Molecular Characterization Facility (MoSE 1241)
**** Interested users must login to the Shared User Management System (SUMS) and request access to the Instrument Group "STAMI" ****
The polymer and molecular characterization facility is a collection of instruments by STAMI faculty members with the capability of measuring: 1) molecular weights of polymers by GPC at ambient and high temperatures; 2) sizes of macromolecular particles by DLS; 3) liquid-solid surface interface properties by contact angle measurement; 4) the absorptive properties of solutions, solids, and thin films from UV to the near IR wavelengths; 5) infrared absorption properties of solutions, solids, and thin films; 6) fluorescent and phosphorescent properties of solutions, solids, and thin films at variable temperatures; and 7) thermal properties such as glass transition temperature and thermogravimetric properties with DSC/TGA.
The Polymer and Molecular Characterization Facility is currently is located in the Molecular Sciences and Engineering building (MoSE 1241) and operates as a cost center to increase usage by the broader Georgia Tech community. If you are interested in using the facility, please login to the Shared User Management System (SUMS) and request access to the Instrument Group "STAMI". Instrument training, scheduling, and billing for the STAMI Lab is all handled through SUMS. Educational, Government, and Industrial users may request access by contacting us, external billing rates apply.
