| Instrument | Analyses available | Sample types |
|---|---|---|
| Ion chromatograph (IC) | Anion concentrations (fluoride, chloride, bromide, sulfate, nitrate) | Aqueous solutions; see IC for sample requirements |
| ICP-AES | Major elemental composition (>500 pbb) | Aqueous solutions/solids; see ICP-AES for sample requirements. SiO2 analysis requires lithium metaborate fusion. |
| ICP-MS | Trace elemental composition (<200 ppb) | Aqueous solutions/solids; see ICP-MS for sample requirements |
| IRMS | Stable isotopic composition (δ13C/δ18O/δ15N) | Organic material/carbonate minerals/carbon dioxide gas/dissolved inorganic carbon; see Delta V IRMS for sample requirements |
| MC-ICP-MS | Metal isotopic composition (Ca, Cu, Mg, Fe, Li, U, etc) | Digestates in acidic solution; purified by ion exchange chromatography; see MC-ICP-MS for sample requirements; digestion & purification can be done by LIME for added cost |
| TIMS | 87Sr/86Sr and δ44Ca | Digestates in acidic solution; purified by ion exchange chromatography; see TIMS for sample requirements; digestion & purification can be done by LIME for added cost |
