Facilities - Light Isotope Mass Spectrometry Laboratory
The Light Isotope Mass Spectrometry Laboratory (LIMSL) is a dedicated climate controlled laboratory that houses three stable isotope ratio mass spectrometers (two ThermoFinnigan Delta XP's and one Delta V) and a variety of peripheral devices for the analysis of light stable isotopes in both organic and inorganic material. The peripheral devices include two elemental analysers (ThermoFinnigan Flash EA and a Eurovector) for the combustion of samples and measurement of carbon, nitrogen and sulphur isotopes. Additionally, we have a ThermoFinnigan TC/EA (with zero blank autosampler) for the measurement of oxygen and hydrogen and a ThermoFinnigan Surveyor Liquid Chromotograph (LC) and mass spectrometer interface (Isolink) for the measurement of compound specific carbon isotopes in single compounds such as amino acids.
