The Shimadzu IR Prestige attenuated total reflectance fourier transform infrared (ATR-FTIR) spectrometer collects IR spectra from 600 to 4000 cm^-1. The system can be used for liquid, powder and bulk sample analysis. This system also has a scanning AIM 8800 IR microscope attached to it which is operational. However, at present we lack the the software and operational expertise to facilitate its usage. Should a research group wish to utilize the microscope system, the LSBI is willing waive all usage fees in exchange for the generation of coherent standard operating procedure for the instrument.

Zetasizer Nano ZS DLS

The Malvern Zetasizer Nano ZS uses photon correlation spectroscopy (PCS), which determines particle size by measuring the rate of fluctuations in laser light intensity scattered by particles as they diffuse through a fluid, for size analysis measurements and electrophoretic light scattering (ELS), which determines electrophoretic movement of charged particles under an applied electric field from the Doppler shift of scattered light, for zeta potential determination.

Shimadzu UV-2550 UV-Vis Spectrophotometer

The Shimadzu UV-2550, with it's double-blazed grating, double monochomator design, provides a high-energy throughput optical system with ultra-low stray light. While featuring low stray light, excellent energy characteristics are provided over an extremely wide wavelength range (200 - 1100 nm), from the ultraviolet to visible, and into the near infrared for both liquid and solid samples.

Full Spectral Confocal Microscope with Fluorescence Lifetime and Anisotropy Imaging

The Olympus FV 1000 confocal platform allows for full spectral imaging with a variety of excitation options: 405 nm, 454 nm, 488 nm, 515 nm, 543 nm and 635 nm. Single pass three channel imaging is routine on this system, with two of the detectors being monochromator based and one being filter based.

Both 405 nm and 640 nm pulsed laser sources allow for fluorescence lifetime imaging microscopy (FLIM) on the FV 1000 platform using a PicoQuant TCSPC FLIM add-on. Two detectors allow for two color FLIM or for anisotropy decay imaging (A-FLIM).
