Thermal Elemental Analysis (TEA)
A Flash EA 1112 Series Elemental Analyser (EA) connected via a Conflo III to a DeltaPlus XP isotope ratio mass spectrometer (all Thermo Finnigan, Bremen, Germany); for the determination of Nitrogen and carbon isotopes in solid samples such as soil and plant material. The Flash EA can be substituted with a High Temperature Conversion EA (TC/EA) allowing determination of hydrogen and oxygen isotopes.
A Gas-bench II connected to a DeltaPlus Advantage isotope ratio mass spectrometer (both Thermo Finnigan, Bremen, Germany). This allows us to determine the carbon isotopes of carbon dioxide in gases and is commonly used in soil respiration studies. Additionally we can determine the carbon isotopes in substances which can be quantitatively converted to CO2 such as dissolved inorganic and organic matter in waters.
A gas chromatography combustion isotope ratio mass spectrometer system or GC-C-IRMS. This comprises of a GC Trace Ultra with combustion column attached via a GC Combustion III interface to a Delta V Advantage isotope ratio mass spectrometer. This allows us to perform compound specific carbon isotope analysis of phospholipid fatty acids (PLFAs) and alkanes The analysis of PLFAs allows the functioning of soil microbial communities to be investigated.
