The high resolution accurate mass measurements that Orbitrap mass spectrometers provide are particularly valuable for metabolomic tracing experiments, termed “fluxomics” or “stable isotope labeling”. In these experiments scientists introduce stable isotope labeled compounds to create metabolic roadmaps to understand biological pathways and perturbations to systems. A major challenge is to interpret the results of these experiments, but Compound Discoverer software provides unique capabilities to determine isotopic enrichment in an untargeted fashion by leveraging the high resolution accurate mass data generated by Orbitrap instruments. Compound Discoverer software provides easy to interpret results through multiple powerful visualizations including isotopologue distribution charts and customizable overlays of labeling onto biochemical pathways through Metabolika. This powerful approach is an excellent complement to standard untargeted metabolomics and our differentiated products provides unique abilities and insights.

Dear Orbitrap users,
We are running a new series of webinars to familiarize our user-base with more functions in Thermo Fisher Scientific™ Compound Discoverer™ software.
The sessions will vary in topics and suitability to your level of experience. You are welcome to register, and forward to your colleagues, in any or all of the sessions below.
Each session is described briefly here and in detail in the registration link. You may directly register via the link provided for each session. You need to fill a short registration form for each session, but you can save your answers and spare a few clicks if you intend to register for more than one session.
The series will be presented by Elizabeth Crawford, Vincent Jespers and Anas Kamleh.
QuickFix 1 for Compound Discoverer 3.2 is now available for download : https://thermo.flexnetoperations.com/control/thmo/product?plneID=820507 .
It primarily fixes the problem with invalid structures in the Natural Products Atlas Mass List, which sometimes caused a “Cannot create structure from given MOL string” error. We also made a small change in the Mass List Editor to make sure we don’t see this problem again with other mass lists.

GC-Orbi, CD: Gain new impactful insights for your analysis with Thermo Scientific GC-Orbitrap MS and Compound Discoverer 3.2 software
30th Nov 1pm ET – Xin Zheng, Jason Cole
Compound Discoverer is an integrated software platform to handle all your metabolomics data analysis needs including statistics for comparative analysis, unknown annotations, data visualization, pathway mapping, and stable isotope labeling. In this presentation, we will discuss some of the challenges in metabolomics data analysis and take a closer look at the unique tools and flexible workflows in Compound Discoverer that help streamline the data analysis and get results faster. This presentation also includes a preview of the new features in the upcoming version 3.2.
A couple new scripting nodes can be found here.
- Adding an m/z column to the Compounds table
- Adding m/z and Delta Mass [ppm] columns to the Expected Compounds table
- Calculate O/C and H/C ratios in the Compounds table
- Show KEGG IDs (top mzCloud hit) in the Compounds table
Your feedback and requests for additional scripting nodes are welcome!
