Biogeochemistry Lab
Welcome to the Biogeochemistry Lab
where our main research interests include sedimentary geochemistry, marine systems
and biogeochemical cycles - in modern marine environments and ancient settings. Our
current research is centered around trace metal and sulfur cycling in deep marine
trench sediments off Japan. This lab is equipped for trace metal analysis, sulfur
extraction and determination of iron phases.
Our current research includes:
- Early diagenesis in modern marine sediments and it's impact on primary depositional signals
- Subsurface metal cycling and it's implication for the (ultra) deep biosphere
- Investigation and application of paleoproxies with emphasize on redox-sensitive trace metals
- Geochemical cycles of methane, iron, sulfur, and related trace metals in active margin environments
We have high-quality instruments and equipment in our lab
A few of our major equipment are (ICP-MS) Inductivley coupled plasma-mass spectrometer,
Thermo Scientific ICAP Qc (high sensitivity cell mode performance) with Cetac autosampler.
Along with a Carbon/Sulfur Analyzer (CS-2000) ELTRA, with induction and resistance
furnace, and inorganic carbon analyzer module.
We also have sample preparation
along with miscellaneous equipment
- PicoTrace acid sample digestion system (temperature and pressure digestion)
- Ductless polypropylene fume hood (Patriot;Airclean Systems)
- Ductless laminar fume hood (AC600;Airclean Systems)
- Water purification system (MilliQ)
- Acid purification system (Savillex Corporation)
- Analytical Balance (Mettler Toledo) five digit (XSE205DU), and three digit (MS1003)
- Horizontal Air Flow Oven
- Overhead Shaker (Heidolph, Reax 2)
- Ultrasonic Cleaner (Branson)
- Muffler Furnace (Barnstead)
- Centrifuge (Eppendorff, 5810)
- Photometer (Hach)
