MUN PXRF-NIR/SWIR-Microscopy Lab

Research Facility



MUN PXRF-NIR/SWIR-Microscopy Lab
Memorial University
St. John's
Newfoundland and Labrador (NL)

Lab is equipped with an Innov-X X5000 benchtop portable X-ray fluorescence (pXRF) spectrometer, TerraSpec 2 near infrared-shortwave infrared (NIR-SWIR) portable spectrometer, and Nikon LV100 and AZ-100 petrographic microscopes. the pXRF and NIR-SWIR spectrometers allow real-time, non-destructive geochemical and mineralogical analysis of materials. Microscopic instruments are traditional instruments for non-destructive geological material characterization, mineral and mineral textural identification.

Equipment



Portable X-Ray Fluorescence Spectrometer
Innov-X
X5000

The instrument is utilized for real-time, non-destructive determination of analytes in various media. Calibrations have been created for utilization in lithogeochemistry, the geochemistry of surficial materials (e.g., soil, till, stream sediment), and determination of metals in metal-rich samples (e.g., ores, concentrates). User fees apply for utilization and negotiated with the facility. It has been utilized in the evaluation or rock geochemistry in mineral exploration, exploration geochemistry, surficial material chemistry, and sourcing of artifacts in archeological studies.

The instrument is a bench top instrument with Ta X-ray tube and a large area silicon drift detector (SDD).

TerraSpec Near Infrared - Shortwave Infrared (NIR-SWIR) Spectrometer
ASD Inc.
TerraSpec 2

Portable infrared spectrometer for non-destructive real-time mineral identification.

TerraSpec 2 instrument equipped with mug lite and fibre optic wand for real time determination of hydrous and carbonate minerals in geological samples. Lab also contains The Spectral Geologist software (v.7.1) for identification of minerals and quantitative evaluation of absorption spectra. The instrument is routinely utilized for hydrothermal alteration mineral mapping and distribution, and distribution of clay minerals in geological materials.

Nikon LV-100 and AZ-100 Microscopes
Nikon
LV-100 and AZ-100

Nikon LV-100 and AZ-100 microsopes for standard transmitted and reflected light microscopy of geological materials.

Nikon LV-100 contains standard transmitted and reflected light capabilities with 2.5x, 10x, 20x, 40x, and 100x lenses and is equipped with a differential interference contrast (DIC)/Nomarski prism for sample topography; the latter is particularly useful for studies of mineral hardness and zoning. 

Nikon AZ-100 is a wide angle, low power microscope for macro-textural evaluation of thin sections and is equipped with transmitted and reflected light capabilities and 0.5-2x lenses. 

Both microscopes have software for digital image capture and manipulation.
