A2 Technologies has introduced two diffuse reflectance mid-infrared spectral libraries of rocks and minerals to extend the utility of handheld FTIR analysers for geoscience applications.
The first library contains spectra of general rocks and minerals sourced from around the world, while the other is focused on commercially important or strategic minerals.
Flexscan and Exoscan FTIR analysers offer performance characteristics that are applicable to field-based geoscience investigations.
The analysers are equipped with diffuse reflectance sampling interfaces, thus enabling rocks, minerals and soils to be analysed with minimal, or no sample preparation.
Now, minerals of interest located in outcroppings, ore bodies, drill cores and mines can be analysed directly at the locale.
According to A2, the capability of FTIR to elucidate how atoms are bound together to form the chemistry of rocks and minerals is an important complement to widely used handheld XRF analysers, which identify the elements that comprise the geological sample.
The diffuse reflectance infrared spectra of rocks and minerals are different than those contained in existing classical transmission IR libraries.
For this reason, A2 Technologies is building these diffuse reflectance libraries in support of its efforts to bring FTIR analysers to geoscience applications.
A2 analysers allow users to create their own diffuse reflectance IR libraries to meet the requirements of their particular area of interest.
