Electron microscopes can excite electrons to form images that magnify micron and nanostructures up to 10 million times, providing amazing levels of fine magnification and allowing researchers to observe even individual atoms. CD BioSciences can provide innovative solutions for electron microscopy and microanalysis. We offer Cameca SXFive Electron Microprobe instruments that allow customers to combine high-resolution imaging with physical, elemental, chemical and electrical analysis to obtain usable data from the widest range of samples.
The Electron Microprobe is a very powerful tool that uses certified standards and X-ray analysis to accurately identify and quantify major and minor element concentrations in a polished sample at the spatial resolution of an electron beam instrument.
The Wavelength Dispersive Spectrometers (WDS) equipped on the microprobes allow for superior X-ray energy resolution over typical EDS detection used in a Scanning Electron Microscope (SEM). The extended stage movement allows for x-ray mapping in which the spatial distribution of elements can be recorded over a large area revealing information about chemical zonation. Microanalysis using the Electron Microprobe can be applied to a wide range of materials including: geological samples, biomaterials (bone and teeth) and engineered materials (metals and ceramics).
The microprobe, sometimes referred to as EMP (electron microprobe) or simply "probe" - are equipped as follows:
1. Tungsten source
2. Five wavelength dispersive spectrometers with 140 mm Rowland circle and the following analysing crystals and detectors:
1) LTAP/LPET, P10 detector
2) PET/TAP/PC0/PC2, P10 detector
3) LPET/LLIF, HP P10 detector
4) TAP/LPET, P10 detector
5) LPET/LLIF, HP P10 detector
3. Computer control by Cameca Peak Sight 6.1 and Probe Software Inc. "Probe for EPMA" and "Probe Image" software packages
4. Integrated Röntec X-Flash 5010 Be-window SDD EDS with Bruker Quantax 2.1.1 Esprit software (elements Na-U)
5. Cameca SE, BSE and CL detectors
6. Built-in reflected light optical microscope
7. Oil-free vacuum system with ion, turbomolecular and scroll pumps
Recommended Sample Size:
1. Polished Blocks - Different resin mount holders allow 3× 35mm or 6× 25mm diameter samples at one time. Blocks must have a 20mm max height but ideally ~10 mm.
2. Polished Slides - Slide holder allows up to 3× 47 × 25mm, 1× 75 × 50mm, OR 1× 75 × 25mm at a time.
