|Application||The BioMedical Metabolomics Facility Leiden (BMFL) offers a highly structured environment for advanced metabolomics studies. BMFL builds on fully validated, state-of-the-art platforms that each cover a part of the human metabolism and together span the complete human metabolome.|
|Availability||BMFL is particularly geared towards biomarker discovery of human disease and health. BMFL works according to ISO17025 guidelines and employs rigorous quality standards, working with well validated methods and using our quality control pipeline which provides correction for analytical variation, data monitoring by means of quality control reports and data standardization. This ensures robust data that enables truly comparative studies.|
BMFL is the core facility of Leiden University and the Netherlands Metabolomics Centre (NMC) and its users include internal as well as external academic collaborators and pharmaceutical and industrial clients from all over the world, measuring over 15,000 profiles annually. BMFL does not only perform routine measurements, but operates at the frontier of metabolomics developments and opportunities. The BMFL team covers the complete track from involvement in experimental design, study set-up and sample collection to the actual measurements, data analysis, identification of unknown compounds and comprehensive feedback on the results. In close collaboration with partners, BMFL defines a tailor-made approach that offers the best fit between your biological question and optimal use of the potential of our highly advanced facilities.

Being embedded in the university ensures that new technological opportunities are quickly recognized and further developed into new platforms. The BMFL portfolio is therefore continuously improved and expanded. Major research efforts in miniaturizing methods, increasing sensitivity and coupling to organ-on-a-chip are currently being done jointly with researchers in the division of Analytical Biosciences.
Together with the Metabolomics Research lab of the Division of Analytical Sciences, led by prof. Thomas Hankemeier, the facility hosts more than 15 mass spectrometers, comprising ion-trap hybrids with FT-ICR and FT-Orbitrap, Q-ToF, Q-ion mobility-ToF, Triple quadrupole.
