In recent years the School of Chemistry in TCD has strategically acquired improved NMR and mass spectrometry and high specification X-ray diffraction research facilities, items of equipment that may be considered the work horses of structural elucidation in synthetic chemistry. See individual webpages for further information.
In addition to equipment targeting the structural elucidation of materials the School also has a number of instruments of general research spectroscopic equipment used extensively for the characterisation of novel materials including nano-materials and the study of biophysical systems.
- Circular Dichroism Spectrometer: Jasco J-810 Spectropolarimeter
- UV-visible spectrometer: Cary 300 Scan dual beam, 6´6 Multicell Block Peltier Temperature Controlled
- FT-NIR instrument: Perkin Elmer Spectrum One NTS with ATR Sampling Accessory
- Fluorimeter: Cary Eclipse and a Perkin Elmer LS-50B
These instruments are complemented by further facilities in individual research groups. Conscious of the importance of such spectroscopic equipment the School has moved to address this deficit by moving to establish a comprehensive suite of equipment. A recent application to the HEA succeeded in securing a number of instruments which will enhance the Schools research in materials spectroscopy, allowing the characterisation of a wide range of systems, in particular in the area of materials and biophysical chemistry.
This equipment includes a basic UV-emission suite capable of low temperature and spectroelectrochemical measurements that will act as an analytical platform from which more specialized measurements can be carried out. This will be enhanced by the Circular and Linear dichroism instrument for the characterisation of optically active systems and the UV-NIR and NIR-PL instruments which have expanded spectral ranges suitable for the characterisation of recently discovered bio- and nano- materials.
- UV-vis and Fluorescence spectroscopy suite with Optical Cyrostat Chamber and Spectroelectrochemical facility
- Near Infrared Steady State Fluorimeter with ns lifetime counting
- NIR- UV-vis (175-1800 nm) Spectrophotometer
- J-815 Circular Dichroism Spectropolarimeter with Linear Dichroism Accessory
The development of such a comprehensive spectroscopy suite ideally positions the School of Chemistry in TCD to act as fundamental platform for spectroscopic characterisation in the College that can interface with complementary techniques in both the CRANN institute and the School of Biochemistry and Immunology.
In addition to the spectroscopic instruments highlighted above the study of materials chemistry is also facilitated by the use of Transmission and Scanning Electron Microscopy in the Central Microscopy Laboratory (TCD), as well as microscopy instruments in individual research groups. Other equipment for the analysis of materials in the School includes light scattering, thermogravimetric and calorimetry analysis equipment:
- Dynamic light scattering: Malvern Zeta Sizer Nano ZS allows determination of the size of nanomaterials in solution in range 0.6 nm to 6mm. The instrument also allows measurement of zeta potentials.
- Thermal Gravimetric Analysis: Perkin Elmer Pyrus 1 TGA equipped with an ultra-micro balance with a sensitivity of 0.1 microgram. The temperature range is from 30oC to 1000oC with a scan rate from 0.1oC/min to 100oC/min. Routinely used to determine the decomposition of a material in a given environment.
- Differential Scanning Calorimeter: Perkin Elmer Diamond DSC equipped with an intracooler to allow a temperature range of -30oC to 700oC. Used to measure the melt, crystallisation, glass transition temperatures and monitor reactions.
Miscellaneous items of equipment in the School include a Beckman DNA synthesizer, a small number of HPLCs and GC instruments, an Olympus stereo-microscope with camera attachment as well as the recent funding of a CEM Discovery S-Class Laboratory Microwave with autosampler to permit the rapid and automated production of compounds associated with areas of strategic importance including: Anti-cancer compounds, anti-addictive compounds (neuroscience) and compounds of interest in the area of nanoscience.
