The LSU Department of Chemistry Polymer Analysis Facility (PAL) occupies 1500 sq ft on the 2nd floor of the Chemistry building.  A full-time Ph.D.-level staff employee supports the facility.  The Facility is managed by Dr. Rafael Cueto ( 

The Polymer Analysis Laboratory provides advanced equipment for characterization of macromolecules, supramolecular assemblies, colloids, complex fluids, and related materials.

Distribution of polymer molecular weight and size can be measured qualitatively or absolutely on one of 2 Agilent-Wyatt and a Tosoh EcoSEC Gel Permeation Chromatography - Multi Angle Light Scattering (GPC-MALS) systems

Dynamic light scattering can be performed on a state-of-the-art laser light scattering systems built to the specifications of the department in LSU’s Scientific Instrumentation Shops, on a Malvern ZetaSizer (which can also measure zeta potential) or on-line in flow-through mode using a Wyatt QELS.

PAL’s thermal analysis facility (TA Systems) includes Differential Scanning Calorimetry (DSC, two instruments), Thermo Gravimetric Analysis (TGA), and Dynamic Mechanical Analysis (DMA)

PAL’s optical microscopy facility is equipped with Olympus and Leitz optical microscopes for polarized, transmission, and epi-fluorescence illumination. with video cameras interface to two separate image processing systems.

Other instrumentation includes a NIMA Langmuir Blodget trough, equipped for surface pressure measurement and production of thin films, a Beckman Coulter LS-200 Laser Diffraction Particle Size Analyzer, an Agilent 8453 UV-Vis Spectrophotometer, and a Perkin Elmer LS50B Luminescence Spectrometer
