The Dove Group possesses a wide range of state-of-the-art research equipment – take a look at our different instrumentation tabs below.
For more details on any of the equipment or to enquire about availability, please contact Senior Lab Technician Dan Smith via D.P.Smith@bham.ac.uk
JPK Nanowizard 4 AFM
With acoustic heated enclosure and accessories.
The atomic force microscope (AFM) allows high resolution imaging at nanometre length scales. It scans a prepared surface with a tip that is deflected by the presence of features with different heights. The deflection is measured by bouncing a laser beam off the back of the tip and recording its movement using a photodiode detector.
Malvern Nanosizer Nano-S
With Malvern Instruments Multi-purpose titrator MPT-Z
Malvern Zetasizer Nano-ZS
The group has two DLS, a Malvern Zetasizer Nano-S and a Malvern Zetasizer Nano ZSP.
Dynamic light scattering is a technique in physics that can be used to determine the size distribution profile of small particles in suspension or polymers in solution.
The DLS is used for particle sizes down to 1 nm diameter.
STATIC LIGHT SCATTERING (sls) – ALV/CGS-3 Compact Goniometer system
STATIC LIGHT SCATTERING (sls) – ALV/CGS-3 Compact Goniometer system with ALV/LSE-5004 autocorrelator
The ALV/CGS-3 Compact Goniometer system is designed to record and measure simultaneous dynamic (DLS) and static (SLS) light scattering data. The basic principle behind this technique is to illuminate a dispersed sample solution with a laser beam of known wavelength (in this case λo = 633 nm) and to detect the intensity of light scattered by the sample. If the light scattering data is collected as a function of time, nanostructure dynamics can be analysed as in the case of DLS. Alternatively, averaging the scattered intensity over a chosen time scale which is much greater than those in which solution dynamics occur results in light scattering based on particle size and shape as in the case of SLS. Further to this, by collecting data over a range of angles it is possible to estimate dimensional properties of nanostructures contained in solution, e.g. the mass average molar mass (Mw), the radius of gyration (Rg) and hydrodynamic radius (Rh).
Mastersizer 3000 with the Hydro MV wet dispersion unit
The Mastersizer 3000 uses the technique of laser diffraction to measure the size of particles (0.01–3500 µm). It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. It is equipped with the Hydro MV accessory for the analysis of wet dispersions in either aqueous or non-aqueous solutions.
PSS (Polymer Standards Service) Differential Refractometer Dn/Dc 1260
The Differential Refractometer enables a very precise determination of refractive index increments (dn/dc) of dissolved substances in highly diluted solutions.
