Stable isotopes
O-isotope measurements 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, powders or 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.
