ATR objective

Our diverse, interdisciplinary research require a wide variety of instruments.  Please scroll down or click the links on the left to find out more about our spectrometers, spectroscopic accessories and other apparatus.

Bruker and Agilent FTIR imaging systems

The FTIR spectroscopic imaging systems couple FTIR spectrometers with liquid-nitrogen cooled MCT Focal Plane Array (FPA)  detectors with 64x64 or 128x128 pixels, allowing multiple spectra from different spatial locations to be acquired simultaneously.  The FPA detector can be placed in a macrochamber or large-sample compartment, allowing a variety of transmission or ATR accessories to be used, or in an infrared microscope, for high-resolution ATR and transmission/reflection imaging.

Single-element FTIR spectrometers

All our FTIR imaging systems are capeable of single-element measurements (i.e. the acquisition of a single infrared spectrum), but we also have dedicates single-element spectrometers.  These allow for quick measurements of samples in ATR and transmission modes and are also ideal for extremely fast kinetic experiments, and experiments where the spatial distribution of components is not required, such as well-mixed liquid phase reactions.

High Pressure and Supercritical Fluid Apparatus

High-pressure and high-temperature experiments are possible using the ISCO pump, high-pressure generator and gas flow cell on a heated diamond ATR accessory.  These conditions enable experiments with super-critical CO2 and other novel materials.

Confocal Raman and FT-Raman

Our Renishaw confocal Raman system (dispersive) allow spectra to be obtained from different depths within the sample and its X-Y stage also facilitates automated mapping of samples.  The FT-Raman spectrometer is connected to a Bruker Equinox 55 spectrometer for fast characterisation of materials and large area measurement.

Confocal Raman
The Renishaw Raman system with confocal microscope contains a 514 nm 20mW argon laser, and a 785 nm 300mW diode laser. The microscope contains 5x, 20x, 50x and 100x dry objectives, as well as a 50x and a 100x oil immersion objective.

NTMDT NTEGRA Spectra AFM/Raman system

Our AFM/Raman system with upright and inverted microscope enable the phenomenon of tip-enhanced Raman to be exploited for a variety of samples, with laser illumination from the top or underside of the sample.  The presence of the AFM tip near the sample surface within the beam of Raman laser gives an enhanced Raman signal from the tip, giving a spatial resolution well below the diffraction limit of the laser.

AFM-Raman system
The NTEGRA Spectra AFM-Raman system contains a 473 nm 100mW laser, and a 633 nm 50mW laser for acquiring Raman spectra with a microscope that can be used in upright or inverted modes.

Microdroplet system

The microdrop device enables the deposition of small volume (approx. 110 pL) of liquid samples at precise locations.  Liquids can be heated up to 160 ˚C and so this device can also be used to print wax patterns to create 3D micro structures.
