Inductively-Coupled Plasma (ICP) Lab
Inductively-coupled plasma mass spectrometry (ICP-MS) is a powerful technique for the quantification of minor and trace elements present in natural and experimental samples at very low concentrations.
Our Facility houses a brand new Thermo Scientific iCAP Q ICP-MS equipped with an autosampler for the analyses of bulk samples in solution, as well as a NewWave 213 nm ND-YAG laser ablation system for the analyses of solid samples. Our class-100 clean room allows for sample and standard preparation in an environment free of possible contaminants.
For more information on our ICP-MS facility, services offered, and contact information please visit the ICP Lab .
Isotope Biochemistry Lab
This laboratory is focused on measuring lipid biomarkers and greenhouse gases and their isotopic composition, as well as C and O isotope ratios on carbonates. Key capabilities include:
- Wet lab with facilities for extracting and purifying lipids from sediments and other samples, including a microwave solvent extraction system (CEM MARS 6), solvent evaporation units, and hoods for column chromatography
- Gas chromatograph-flame ionization device (Thermo Trace 1310) for quantification of lipid biomarkers and hydrocarbon gases (e.g. CH4)
- Gas chromatograph-isotope ratio mass spectrometer (Thermo Delta V Plus with GC-Isolink) for carbon and hydrogen isotope measurements of lipid biomarkers and hydrocarbon gases (e.g. CH4)
- Cavity ringdown greenhouse gas carbon isotope analyzer (Picarro G2201-i) for 13C measurements of CO2 and CH4
- Cavity ringdown water isotope analyzer (Picarro L2140-i) for water isotope analyses (including 18O, 2H, and 17O)
- Mobile greenhouse gas concentration analyzers (Picarro Gas Scouter G4301) for high precision mobile surveys
- A Nu Instruments Perspective large-radius mass spectrometer is equipped for both dual inlet and continuous flow analyses. It is coupled to a NuCarb automated carbonate preparation device for highly precise and sensitive measurement of carbon and oxygen isotope ratios in carbonate minerals.
