  • Spectro Arcos OPI ICP-OES
  • Axial View system designed for high sensitivity, coupled with a CCD optic system with a Paschen-Runge mount assembly allowing for a wavelength range coverage from 130 to 770 nm. Resolution is 8.5 picometer in the range of 130-340 nm and 15 picometer for higher wavelengths.
  • Two modes of operation:
    • Coupled with Teledyne Photon Machines 193nm UV laser for solid sampling (see in situ geochem)
    • Coupled with Teledyne Cetac ASX-520 autosampler for solution analysis (e.g. bulk rock digestions or water samples)


Suitable for both major element geochemistry (wt% major oxide determinations) and trace element analysis (ppm) of natural materials.

Additional information:

Supported by the General Laboratory for all sample preparation, including LiBO3 fusion and acid digestion.
