UCL Chemistry Mass Spectrometry Facility (BEIF)

The Bloomsbury Environmental Isotope Facility (BEIF) is a central UCL facility jointly founded in 2002 by Chemistry, Geography and Earth Sciences (SRIF 1, 2, 3 funding, £676k) within Chemistry's Mass Spectrometry Laboratory (headed by Prof. T. Atkinson). It is equipped to measure stable isotopes in water, soils, rocks and sediments (three Thermo-Finnigan isotope ratio mass spectrometers, below) and environmentally occurring radio-isotopes (three Ametek gamma spectrometers for 210Pb dating, Octete alpha spectrometer for uranium-series dating and TriCarb2900LR scintillation counter for environmental radioactivity). BEIF supports research on water resources, climate change and aquatic ecosystem change.

Instruments

Thermo Finnigan MAT253 The Thermo Finnigan MAT 253 (purchased in 2004) delivers high sensitivity and precision for determining isotope ratios. Seen as the top-of-the line isotope spectrometer the instrument measures isotope ratios of: H/D, 13C/12C, 15N/14N, 18O/16O, 34S/32S. It can also determine isotope ratios of 28Si/29Si, Ar, Kr and Xe.
Thermo Finnigan Delta V Advantage Installed in 2005, the Thermo Finnigan Delta V Advantage is the newer version of the Delta plus XP (see below). Operational in Dual Inlet and Continuous Flow modes and with, or without Helium supply.
Thermo Finnigan Delta Plus XP The Thermo Finnigan Delta Plus XP is equipped with an Elemental Analyzer for determining isotope ratios of Nitrogen and Carbon in solid samples.

Service

We also provide a Mass Spectrometry Service for the Chemistry Department, other UCL Departments and External Organizations.
