SpecMIN mineral spectra library now available with EZ-ID software for oreXpress portable spectrometer

Posted by Daniel Gleeson on 9th December 2013

EZ-ID software running on an oreXpress portable spectrometer is one solution for fast, easy, and accurate mineral identification in the field. EZ-ID matches the unknown mineral against a known spectral library and is now available with the SpecMIN library from Spectral International. SpecMIN includes an extensive and dynamic library of over 494 infrared active mineral species with more than 1,528 individual spectra. This unique spectral library includes a minimum of two different samples per mineral. With the availability of the SpecMIN library, EZ-ID software can be used for real time mineral identification with outcrops, in pits, with hand samples, and is especially useful in  fast and accurate core logging applications.

EZ-ID features include:

  • Fast and accurate identification of an unknown mineral to a known library sample
  • Ease of use – just collect a target scan using the oreXpress spectrometer and see immediate match results in real time
  • Simple, consistent user interface
  • Include or exclude spectral regions of interest for optimal results
  • Fast scanning for optimum field work or core shack logging

The company states: “With our Custom Library Builder software module, EZ-ID allows you to scan known samples and quickly build a custom library for a particular project, mineral, location, and more. You can select pre-defined metadata fields or define your own. The combination of EZ-ID software and the oreXpress field portable spectrometer for mining offer geologists a complete mineral identification system to improve mining exploration.”

The oreXpress spectrometer with companion GETAC PS336 handheld microcomputer features a 350-2,500 nm spectral range and auto dark shutter and autoexposure for easy, one-touch scanning; while no optimisation is required to start scanning. With the GETAC PS336, it is possible to easily tag spectra with images from the auto-focus digital camera, e-compass, altimeter, GPS data, and voice notes. The GETAC has sunlight readable VGA display; mineral contact probe with metal-clad fibre optic cable; lightweight Li-ion batteries for power in the field; and accessories including core shack fold-up field cart and benchtop reflectance probe.
