Gas Chromatograph with Headspace Sampler


Gas Chromatograph with Headspace Sampler

Agilent 7890B Gas Chromatograph - Mass Spectrometer 5977A - Halocarbon gases concentrations

Volatile halocarbons, such as methyl iodide (CH3I), are purged and trapped on an IMT VSP4000 system, then the isolated compounds are carried to a gas chromatograph (GC) equipped with a micro electron capture detector (ECD) and a mass spectrometer. This instrument measures methyl idodie (CH3I), chloriodomethan (CH2ClI), diiodomethan (CH2I2), dibrommethan (CH2Br2) and bromoform (CHBr3).

The cycling of the three key chemical controls on life in the ocean (carbon, oxygen, & nitrogen) is undergoing unprecedented change in the oceans as a result of human activities. We aim to observeunderstand, and predict complex interactions within these biogeochemical cycles, which will help us understand the implications of these changes for marine life and the climate. 

The CERC.OCEAN laboratory is focused on chemical oceanography and in the measurement of greenhouse gases, such as nitrous oxide, carbon dioxide and halocarbons. The laboratory is equipped with high-tech instruments, such as isotope ratio mass spectrometers, gas chromatographs, cavity ring down spectrometers and nutrient autoanalyzer.
