Facility Description for Proposal Preparation

The LSU Shared Laboratory for Macro and Bio-Macromolecular Research (SLMBR) 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 Manager is Dr. Rafael Cueto (  

The SLMBR 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 two Agilent-Wyatt gel permeation chromatography Multiangle Light Scattering (GPC-MALS) systems, or a Tosoh EcoSEC Elite GPC system with a LenS3 MALS Detector.

Dynamic light scattering measurements 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, or a Malvern ZetaSizer nano ZS instrument (which can also measure zeta potential). On-line in flow-through mode is also available using a Wyatt QELS.

SLMBR’s thermal analysis facility includes Differential Scanning Calorimetry (DSC) (TA Instruments Discovery DSC 250 and Q200), Thermogravimetric Analysis (TGA)( TA Instruments Discovery TGA 550), Dynamic Mechanical Analysis (DMA)( TA Instruments Q800), and Rheology (TA Instruments Discovery HR-20, and Ares AR200).

SLMBR’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.
