Organic Microbial Geochemistry Lab

Processes related to the solvents extraction of snow and ice algae or particles are conducted in the Organic Microbial Geochemistry Lab. These processes are done in combination with ultrasonic bath, shaking, and solid phase extraction. Evaporation of organic extracts using nitrogen or argon gas, as well as various intermediate steps such as milling, acidification and filtration are also carried out in this lab. The subsequent analysis is done with the Shimadzu Total Organic Carbon Analyzer (TOC-L-CPH) with ASI-L Autosampler or FT-ICR Mass Spectrometer (FT-ICR MS). For the latter, measurements are done in collaboration with Section 3.2 or with external partners at the Research Group for Marine Geochemistry of the University of Oldenburg or the Ion Cyclotron Resonance Facility of The National High Magnetic Field Laboratory.
