Imaging and analysis techniques
CHN elemental analysis
In CHN elemental analysis solids are combusted and the resulting oxides of carbon, hydrogen and nitrogen are analysed chromatographically.
Electron probe microanalysis (EPMA)
The Cameca SX100 is a dedicated wavelength-dispersive X-ray electron microprobe that performs quantitative elemental analysis of samples while left unattended overnight.
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS)
The (ESI) New Wave UP193FX laser ablation system is coupled to the Agilent 7500cs ICP-MS to provide a dedicated LA-ICP-MS system that can perform quantitative trace element analysis of solid materials and U-Pb age determinations in accessory mineral phases.
Micro-computed tomography (CT)
Micro-CT is a non-invasive and non-destructive technique that uses X-rays to create 3D models of the internal and external features of specimens. More than 3,000 X-ray projections are taken over a 360° rotation. A greyscale 3D volume is created, where the grey level reflects the X-ray 04C0 attenuation of the material being scanned.
High-resolution scanning electron microscopy
The Museum's imaging facility has two scanning electron microscopes (SEMs) capable of high-resolution imaging. Follow the links below to discover key features and technical details, see examples and find out which would be most suitable for your applications.
In this technique a Nikon Eclipse upright microscope is coupled to a Nikon A1-Si confocal microscope to scan an object using a laser beam to build up the image a line at a time.
Variable pressure scanning electron microscopy
The Museum's imaging facility has three scanning electron microscopes (SEMs) that can work at variable pressures. Find out about their key features and technical details, see examples and find out which would be most suitable for your applications.
Transmission electron microscopy
The Museum uses the Hitachi H-7100 transmission electron microscope (TEM), which is specially designed to prevent beam damage to delicate and sensitive specimens. Discover more about the instrument and technique.
