I manage the mass spectrometry core facility, part of the Edinburgh Clinical Research Facility. We focus on small molecule analysis using triple quadrupole mass spectrometers. We have expertise in quantitative steroid analysis using chromatography and mass spectrometry, in particular glucocorticoids, estrogens and androgens. We are also able to develop assays for many small molecules including drugs, other lipid like molecules and metabolites of endogenous and exogenous molecules.
