FU - Freie Universität BerlinThe TOC-L Shimadzu device measures total organic carbon (TOC).
AWI - Alfred Wegener InstituteThe hydrochemistry lab at AWI provides wet chemistry analyses of surface and ground waters, snow, ice and permafrost pore water samples. We have optimized the workflow for thawing samples and extracting pore water sediment from sediments and soils for further analysis. We analyze concentrations of major dissolved species in cationic, anionic and total dissolved form, and perform analyses of organic carbon. Standard parameters, such as pH, alkalinity and electrical conductivity of samples are …
GFZ - German Research Centre for GeosciencesProcesses 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 …
UP - University of PotsdamAn instrument (Elementar varioTOCselect) for measuring different carbon fractions (TOC, NPOC, TC, TIC) can be used for the analysis of both liquid and solid samples. The determination limit of the system is 1 ppm.
