Escsis-Earth Systems Center for Stable Isotopic Studies

Samples:
Solid, inorganic: Barium sulfate, Silver Phosphate, Silver Nitrate
Solid, minerals: Hydrous minerals, e.g. biotite
Solid, with additives: Silicates with KF or PTFE
Solid, organic: Sugars, alkanes, etc.
Liquids: "Cold weld" capsule sealer, autosampler for water runs

Sizes: 4 umoles O per sample, solids:3.5x5 mm silver capsules
~200ug barite, silver phosphate, etc.
~150ug silicates with 300ug KF (more if using PTFE)

Stuff: TC/EA with integral GC column
    Conflo III, CO and H₂ reference gases, sample dilution
    Costech Zero Blank autosampler (solids, 49 runs)
    CTC Pal autosampler (liquids)
    Cold trap (liquid N₂, bake out after use)

Availability: Set up dependant
    Can not run phosphates after barites
    Runs with KF or PTFE must use freshly packed reaction tubes
    Limited biotite and silicate standards available in lab
    Phosphate work done in conjunction with Dr. Ruth Blake’s lab.
