Competence Centre “Isotopes in Environmental and Biosciences”

• Analysis of terrestrial biogeochemical cycles using stable isotopes
• "Environmental Forensic" for analysing sources, transport and sinks of (anthropogenic) contaminants
• Characterisation of the water cycle

Laboratory for Stable Isotopes Leipzig (LSI)

• 2 GC/C IRMS for 13C and 15N (MAT 252)
• 2 GC/C/Pyr IRMS for 13C, 15N and HD (MAT 253)
• EA and HTP interface for solid samples connected via ConFlo III to MAT 253
• LC-Isolink IRMS (delta plus XP) for development of HPLC applications
• 2 GC-MSD for testing of the samples before starting the isotope measurements
• GC-FID for measurement of degradiation curves without isotope measurements
• Gas-Analyzer for high enriched samples
• furthermore for development of ³⁷Cl method

Laboratory for Stable Isotopes Halle (LSI Halle)

• 48 port equilibration unit with isotope ratio mass spectrometer (Delta S) for δ²H and δ¹⁸O of fresh water
• elemental analyser for solid samples connected via ConFlo III to isotope ratio mass spectrometer (Delta S) for δ³⁴S of sulphates, e lemental sulphur and sulphides
• high-temperatur pyrolysis for solid and liquid samples connected via ConFlo III to isotope ratio mass spectrometer (Delta XLplus) for δ¹⁸O of nitrate, phosphate, sulphate, for δ²H of cellulose nitrate, and for δ²H and δ¹⁸O of (small sized) water
• elemental analyser with ConFlo III for solid samples OR Gasbench II connected to isotope ratio mass spectrometer (Delta Vplus) for δ¹³C and δ¹⁵N of organics (e.g., sediments), for δ¹³C of carbonates, dissolved organic and inorganic carbon, for δ¹⁵N of ammonium, and for δ¹⁵N and δ¹⁸O of nitrate
• 2x high-temperatur pyrolysis for solid samples connected via ConFlo III to isotope ratio mass spectrometer (2x Delta S) for δ¹³C and δ¹⁸O of organics (e.g., cellulose, wood)
• Infrared absorption laser system for water samples (Picarro L1102-i) for δ²H and δ¹⁸O of fresh water

along with off-line facilities for preparing

• sulphate and sulphide from water samples
• inorganic sulphate, elemental sulphur, acid volatile sulphur, chromium reducible sulphur, and total sulphur from soils and sediments 
• nitrate and nitrite from water samples
• ammonium from water samples
• cellulose and cellulose nitrate from wood/organic material
• highly saline water for isotope analysis

Need to be discussed, depending on joint research interest or projects
