Enabling scientific discovery through stable isotope analysis
Facilities
The IsoLab is a consolidated unit of an instrumentation laboratory, a sample preparation laboratory, an in-lab ice core processing / sample storage freezer laboratory, a hydrofluoric acid laboratory, repair / storage laboratory, in-lab office space, and, two outdoor redundantly cooled storage freezers. We regularly, and graciously, use Quaternary Research Center storage freezer space and library conference room.

Instrumentation Laboratory:
The instrumentation laboratory is 890 sq ft and currently has five isotope ratio mass spectrometers and three cavity-ring-down spectroscopy lasers devoted to the isotopic analyses of hydrogen, carbon, nitrogen, oxygen, and sulfur. Each instrument is computer controlled with Windows based software. Two additional computers are housed for data reduction, storage, and backup. This lab also has a chemical fume hood and compressed gas cylinder rack. Below are links to each method currently running.

Sample Preparation Laboratory:
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, two microbalances, three coarse balances, three drying ovens, one muffle furnace, a refrigerator, two fume hoods, a reciprical shaker, and flexible lab bench space. Below are links to the vacuum sample preparation lines.

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.

Hydrofluoric Acid Laboratory:
The hydrofluoric acid 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.

Repair / Storage Laboratory:
The repair / storage laboratory is 220 sq ft and has a constant volume fume hood, storage cabinets, tools, and a work bench.

Outdoor freezers:
The two outdoor redundantly cooled storage freezers are 300 sq ft each and are held at -35 *C. One of these freezers has a small isolatable front room for sample processing.
