Spectral Technology.

Spectral technology can include a vast array of instrumentation. 

These instruments can be used to analyse a wide range of materials within many contexts. 

Bruker BRAVO Raman

Raman Spectroscopy

Raman spectroscopy is a form of vibrational spectroscopy where the compound or mineral is identified.

This technique is commonly used to identify the structural fingerprint of molecules contained within materials.

Portable XRF

Portable X-ray Fluorescence or Portable XRF as it is commonly known is a technique where energy released from the instrument displaces electrons from their atomic orbital positions within a sample. In this process an outburst of energy occurs. Each elements has a characteristic energy outburst which is registered by the detector of the portable XRF. 

Portable XRF is commonly used to determine what elements are contained within a sample as-well as their concentrations. It is measured as semi-quantitative data.

Fourier Transform Infrared Spectroscopy (FTIR) works when signal released by the instrument. Some of this is absorbed by the sample and some passes through (transmitted). The molecules within the sample will give off a spectral feature or 'fingerprint'.


Molecules produce unique fingerprints, making this method a great way to rapidly identify and verify material.  Instruments such as the Bruker ALPHA II allow the user to create reference libraries which can be used to match unknown materials. 

Different modules such as the ATR, DRIFT and External Reflection allow flexibility when analysing samples. 


By creating custom calibrations using the ATR module allows for semi-quantitative analysis to be performed. 


Short Wave Infrared (SWIR) and Near infrared (NIR) spectroscopy uses light to cause photons to reflect or absorb into an object. 

This technique is great for simple and rapid identification of mineral zonation and information for vectoring at the regional and deposit scale.
