Analytical Facilities

Werne Organic & Stable Isotope Biogeochemistry Lab

Molecular Isotopic Analytical Facilities


The Labs:
​

The organic geochemistry lab includes an automated solvent extraction system (Dionex ASE 350) in a lab with 20 linear feet of fume hood space, and ample bench space to perform any routine organic geochemistry required for extraction and separation of biomarker compounds.

​The molecular isotope lab houses instruments (GC, GC/MS, LC/MS, IRMS) for identification, quantification, and stable isotope analysis of bulk and molecular samples.​

Isotope Ratio Mass Spectrometers (IRMS):

​
We have two Thermo Delta V IRMS instruments capable of C, H, O, N, and S isotope analysis in bulk or molecular samples. Both have a Thermo Trace GC-isolink with combustion and pyrolysis interfaces for molecular C and H isotope analysis.  One has a Costech 4010 Elemental Analyzer for introduction of solid phase bulk samples for C, N, and S analysis, and the other has a Thermo TC/EA for analysis of H and O isotopes in liquid and solid bulk samples.​

LC/MS Instruments:

​
The lab houses two liquid chromatograph/mass spectrometers. Both have a Dionex Ultimate 3000 LC, one of which is coupled to a Thermo TSQ Endura triple quadrupole MS. The other LC is coupled to a Thermo MSQ single quadrupole MS, but also has Fluorescence and Diode-Array Detectors, as well as a fraction collector.

GC and GC/MS Instruments:  

​The lab has two Thermo Trace Gas Chromatographs, which have FID, S-specific FPD, and ECD detectors, as well as a quadrupole mass spectrometer. These instruments are used to identify and quantify biomarker compounds.
