ICP-OES

The SPECTRO CIROS CCD is the first solid-state detector based ICP-OES with continuous 1st Order wavelength coverage from 125 nm to 770 nm in a single 2.5 second measurement. In addition to being capable of analyzing the halogens, the wavelength range allows the measurement of less intense lines for many additional elements. In addition, the SPECTRO CIROS CCD is the first ICP available with a completely programmable positioning system. This Multi-Plasma Viewing goes far beyond the capabilities of simple axial/radial or dual view.

Funding for the instrument was kindly provided by the Canadian Foundation for Innovation, the Atlantic Canada Opportunities Agency, and Freewest Resources Canada Inc.

In-house PASSC Analytical Services

Renishaw inVia micro-Raman spectrometer

Renishaw inVia micro-Raman spectrometer

The micro-Raman (acquired 2007) is equipped with a reflected and a transmitted light microscope. It's useful for chemical identification, characterization of molecular structures, effects of bonding, environment and stress on a sample.

It can rapidly distinguish mineral polymorphs (e.g., kyanite, sillimanite). A micro-precision sample stage permits long-duration mapping.

The micro-Raman is housed and operated by the Planetary and Space Science Centre (PASSC). Contact Dr. John Spray for more information: 506-453-3550 or Email John.

For Students: Please Download the Authorization form and bring it with your samples signed by your supervisor.

Electron and Light Microscopy at UNB MMF

Research in the Department of Earth Sciences Dis supported by in-house electron microbeam instrumentation and a large collection of microanalysis infrastructure centrally located and managed by UNB Microscopy and Microanalysis, a regional facility providing microanalytical and spectroscopic services. 

The MMF is a regional facility provide imaging and analytical services to the University of New Brunswick, other universities, government and industry.

The facility houses three electron-beam instruments (SEM, TEM/STEM, Electron Probe), a confocal scanning laser microscope, digital light microscopes, an X-ray micro CT and a flow cytometer.  

Access to the instrumentation is on a 'first-come, first-serve' basis and users pay an hourly instrument rental fee.  Users have the option in being trained to operate the equipment themselves or in employing the services of the staff of the MMF.

The MMF offers training on all of the instruments and in advanced analytical techniques: EDS, WDS< EELS, EFTEM, electron diffraction, and numerous specialized sample preparation techniques.  Special lectures in microscopy techniques are offered for classroom presentations or for groups of interested researchers upon request.

The UNB MMF lso supports a range of confocol (laser scanning) and digital light microscopes for materials characterization.

For more information, please visit the MMF website.
