Stable isotope measurements

We provide following for service:

  • O-isotope measurements of silicates by laser fluorination ($50/sample)

  • H-isotope measurements and H2O wt.% determination by thermal conversion elemental analysis EA Isolink-OH ($20/sample)

    You will receive a spreadsheet with your sample#, water content (wt.%), δD, δ17O, δ18O and their uncertainties.

Raman microscopy

Identification of minerals - preferably in thin sections and small separated grains ($30/hr)

You well receive a PowerPoint document with identified minerals, their spectra collected in the lab, and optical microscope images with marked spots, where spectra were collected

Microscopic mapping by Raman is available - up to 100 by 100 micron areas
