A variety of analytical and spectroscopic instruments are housed within MC².
Fourier Transform Infrared Spectroscopy (FTIR)
A Perkin Elmer Frontier FTIR instrument is equipped with the following: diamond ATR head, DRIFT attachment for powders, gas cell, transmission cell and an improved resolution MCT detector. It is a bench top instrument used to analyse samples such as hydrocarbons, oils and pharmaceuticals. It can also be used for the determination of surface functional groups.
Raman spectroscopy is carried out on a Renishaw inVia system with a full spectrum of laser sources. The chemical composition and the molecular structure of a sample may be determined, or stress measurements and phase imaging performed. This is a high throughput, non-destructive technique, and although lower in imaging resolution than an electron microscope, offers a more dynamic method for investigating chemical properties of materials ranging from biological cells to semiconductor devices.
Scanning Probe Microscopy
Our Digital Instruments Nanoscope IIIA microscope is used for the study of thin films, the characterization of membranes, and protein studies. It is a multi-functional instrument that will perform specimen imaging and analysis by a number of different methods, including:
- Atomic Force Microscopy
- Magnetic Force Microscopy
- Lateral Force Microscopy
- Force Spectroscopy
- Fluid Cell AFM
We are equipped with a 3Flex by Micromeritics and an Autosorb-iQ-C by Quantachrome Anton Paar, connected to various gases including nitrogen, carbon dioxide and hydrogen. Our gas sorption instruments are used for determining the surface area, the pore size distribution and the surface activity of solids. In physisorption mode, an adsorption isotherm is measured: it represents the number of molecules that are adsorbed on a solid with respect to the system's pressure, ranging from microbars to the atmospheric pressure. The type and range of porosity can be directly read from the shape of the adsorption isotherm.
