Data analysis for metabolomics and small
molecule mass spectrometry.
The Problem: Untargeted metabolomics suffers
from incomplete data analysis
Untargeted metabolomics is a powerful tool for biological discoveries.
However, these discoveries are highly dependent on the quality of analysis of
the raw data. Reliable detection of relevant signals in the raw data and the
correct interpretation of the underlying spectral features are critical for both
exploratory research as well as multi-omic data integration. Reanalysis of
published untargeted metabolomics studies shows omissions of numerous relevant
compounds in original results as well as typical interpretation mistakes. These
results show an unexplored potential of current as well as legacy metabolomics

Solution 1: Our data
We can analyze your raw data and
deliver lists of peaks with peak areas as well as lists of corresponding
compounds with putative identities, where possible. We use our own computational
tools, but the key aspect of the service is manual curation of the results by
experts. We can help you to correct your existing results, find key differences
among samples, or perform an exhaustive data analysis. Avoid omissions and
mistakes in your results. Contact us
to learn more about
the possibilities and benefits of working with us.
