Facilities

The Bergmann Lab houses a Nu Perspective Stable Isotope Mass Spectrometer that allows for precise measurements of δ¹³C, δ¹⁸O, and Δ₄₇ from the smallest samples. The Nu Perspective features the largest mass dispersion of any commercial IRMS, and has mass resolution CNOS and H (m/Δm) > 200 (10% valley).

Clumped-isotope analysis of carbonates (aragonite, calcite, dolomite, CO₃ groups in apatite)

High-resolution images can be taken from 10-1000X magnification on the in-house Zeiss AX10 microscope. High-resolution images of entire thin-sections at 50X magnification can be produced by stitching together hundreds of smaller images.

Microfacies characterization
Thin section creation, petrographic characterization and micro-drilling of carbonate phases, δ¹³C, δ¹⁸O,  and Δ₄₇ phase-specific analysis: $200/sample

The Struers Labotom-5 and Accutom-100 precision cutters and grinders combine with the Struers LaboSystem polisher to enable the creation of quality petrographic thin sections and an optional final polish of down to 1 micron, ideal for electron microprobe analysis.
