Core Services: Molecular Phenotyping: Undirected Metabolomics Lab

About the Undirected Metabolomics Lab

The Undirected Metabolomics Lab is firmly committed to the development of the science of Metabolomics, and discovery of advanced metabolomic techniques. In order to accomplish this goal, we freely collaborate with researchers from all over the world to acquire a diverse collection of sample types and experimental designs.

The Undirected Metabolomics Facility platform is based on four interwoven and fully integrated aspects:

Hardware: Because of its high sensitivity and the specificity of high-resolution mass accuracy, our platforms are Mass spectrally-based. The current generation of mass specs and the software that control them have become so powerful that it is likely that mass spectrally-based platforms will be the workhorses of the science for the foreseeable future, and can solve the major problems. None-the-less, NMR, FTIR, and other physical measurement systems clearly add benefit where mass spec is not sufficient.

Informatics: The science of Metabolomics is far more driven by the required informatics infrastructure than by the actual hardware platform. The informatics aspect begins with a LIMS system capable of tracking samples, their process through the analysis, and the results of their analysis.

Robotics: Humans are too good at thinking and being creative to do the repetitive mundane, and error prone tasks involved in most medium through-put sample handling. By automating processes wherever possible, we are able to reduce error and, thereby, enhance data quality.

Standards-based QA/QC: The use of standards, embedded into all samples and blanks, to continuously monitor all aspects of the sample preparation and analytical processes assures that the overall process may be continually improved. In addition, the ability to always know the level of error in any data set it is possible to design better experiments. Better experimental design yields more better quality information is obtainable from fewer samples.


The Metabolomics platforms designed by Metabolic Analyses follow the dictum of parallel analyses using a variety of detectors and a variety of separation systems. Mass spectrometry, given its high sensitivity, and the richness of physical detail afforded, has always been the primary means of making these measurements. Our platform design has therefore favored a combination of LC/MS, GC/MS, or CE/MS.
