Sample Preparation Laboratory


IsoLab provides students with the opportunity to conduct customized directed research. Students gain hands-on training in all aspects of sample preparation and analysis from “A to Z,” producing high-quality isotopic data from rock, water or ice samples collected in the field.

The sample preparation laboratory is 780 sq ft and has a carbonate digestion / CO2 purification vacuum line, a glass mulipurpose vacuum line, a water fluorination vacuum line, an in-tube combustion vacuum line, two microbalances, coarse balances, drying ovens, one muffle furnace, freeze dryer, refrigerators, two fume hoods, a reciprical shaker, and flexible lab bench space.

Water 17O preparation line

Water Δ17O Preparation Line

We convert H2O to O2 using Cobalt (III) fluoride with subsequent purification and triple oxygen isotope analysis.

Carbonate Δ47CO2 Preparation Line

Carbonate Δ47CO2 Preparation Line

We digest large quantities of carbonate with subsequent purification for Δ47 of CO2 analysis.

Thermo Finnigan MAT253

Low N Archean Rocks Preparation Line

Large quantities of low-N Archean Rocks are prepared for in-tube combustion for subsequent δ15N analysis.

Ice-Core Processing Freezer

The in-lab ice core processing / short-term sample storage freezer is 140 sq ft and is held at -8°C. Samples stored in this freezer are in the process of being analyzed. This cold room has bench space and an Inca band saw for modest ice core processing for water isotope analysis. Ice-core processing is not offered as a service.

Kerogen Extraction Laboratory

The kerogen extraction laboratory is 160 sq ft and has a corrosive resistant fume hood, a Sorvall Evolution superspeed centrifuge, sink with tap water and DI water, and an eye-wash station. Kerogen extraction is not offered as a service.
