Mission

The stable isotope laboratory (BGC-IsoLab) is tasked with stable isotope analyses of a host of different sample types. Equipped with 10 isotope ratio mass spectrometers (IRMS), the BGC-IsoLab routinely analyses δ18O, δ2H, δ13C and δ15N isotopic signatures in solids, liquids and gases. For example, the BGC-IsoLab analyses the isotopic signatures of atmospheric methane and carbon dioxide to produce long term records indicating changing sources and/or sinks of these two prominent greenhouse gases. Furthermore, the BGC-IsoLab analyses the O2/N2 ratio in atmospheric samples to monitor the changing atmospheric O2 concentration. Together with the BGC-GasLab the BGC-IsoLab routinely measures 11 parameters out of 1 liter sample flasks. The BGC-IsoLab aims to provide high quality measurements in order to depict/extract the small natural isotopic variations in atmospheric time series measurements.
