Environmental Stable Isotopes Laboratory
The Environmental Stable Isotopes Laboratory is equipped with Gas Source Isotope Ratio Mass Spectrometer (GS-IRMS, type Delta V advantage, by Thermo) interfacing Gas Bench II and PreCon device capable of measuring C, O and N isotopes of inorganic substances such as water, carbonate deposits, Dissolved Inorganic Carbon (DIC), carbon dioxide, methane, nitrate, nitrite, ammonium, nitrous oxide and dinitrogen. Additional dual-inlet interface is used to measure vacuum line gas products such as fluorinated silicate samples for O isotopes (next door lab). The IRMS has a typical stability range of below 10 ppm, where concentrating of the sample enables a very low detection limit. Dual inlet sensitivity is increased by additional 25% compared to Continues Flow (CF) sensitivity, allowing fundemental science at higher prescion.
These analyses are typically applied in the following research fields of (bio)geochemistry, hydrology and water quality, micro-paleonthology and sedimentology, petrology and mineralogy, paleoclimate, gas exploration, ecology, medical research and more. As such, this lab is cooperating with fellow researches from the department of geological and environmental sciences as well as researches from other institutes.
The laboratory additionaly hosts a Gas Cromatograph with Flame Ionization Detector (GC- FID) capable of measuring C1-C4 alkanes concentration with detection limit of 10 ppmC, as well as GC- ECD (Electron Capture Detector) and a Reducing Compound Photometer (RCP) capable of measuring H2 and CO gases at trace levels (>10 ppb). Sample handling and preparation is carried out in our Environmental Geochemistry Laboratory equipped with hoods, laminated fume hood, spectrophotometers, titrator and aditional electrodes (pH, Redox, DO), autoclave, centrifuge and vacuum line for CO2 extraction (for 14C).
