Particle Sizing

Particle size is most commonly determined by measuring the changes in the intensity of light scattered from a suspension or solution. This technique is commonly known as dynamic light scattering (DLS). This technique is most commpnly used in the study of nanoparticles. Nanoparticles can take on a wide variety of forms including nano-gold suspensions, protein structures and colloids. Generally the particles studed will be between 10 nm and 500 nm in diameter.

Spectroscopy

In its broadest terms, spectroscopy is the study of the absorption and emission of light and other radiation by matter, as related to the dependence of these processes on the wavelength of the radiation. This allows users to discern information on the elemental, structural and electronic nature of materials. The the following types of spectroscopy are avaialable at the Strand Research Facility. Fourier Transform Infrared Spectroscopy (FT-IR) - Bruker Invenio-R FT-IR Spectrometer Fluorescence - Horiba Fluoromax-4 Spectrofluorometer, Horiba Duetta Ultraviolet-Visible-Near Infrared Spectroscopy (UV-Vis-NIR) - Hitachi U400 Energy Dispersive Spectroscopy (EDS) - Oxford Instruments EDX (link below)
