Routine Analyses

Between now and 2016 the Potsdam SIMS lab will develop roughly a half-dozen routine applications that will function in an automated "point-and-analyze" mode.  As these methods become established and the required reference materials are developed the new analytical capabilities will be listed here.  Analytical parameters are approximate and are meant only as a general guide.

Boron Isotope Analyses >> Tourmaline, Glass
Beam Diameter: between 5 µm (for high B contents) and 15 µm at µg/g boron levels
Analysis Time: 4 minutes (tourmaline) up to 20 minutes at low concentrations
Analytical Uncertainty: < 1 per mil

Carbon Isotopes Analyses >> Diamond
Beam Diameter: 8 µm
Analysis Time: 3 minutes
Repeatability: 0.4 per mil

Oxygen Isotope Analyses >> Zircon
Beam Diameter: 8 µm to which a 10 µm raster is applied
Analysis Time: 4 minutes
Repeatability: < 0.1 per mil

Sulfur Isotope Analyses >> Pyrite
Beam Diameter: 8 µm to which a 10 µm raster is applied
Analysis Time: 4 minutes
Repeatability: 0.2 per mil

U-Pb Geochronology >> Zircon
Beam Diamter: between 10 and 25 µm
Analysis Time: 15 minutes
U-Pb Calibration: Typically better than ± 2%
