Compound Discoverer Workshop at the Metabolomics Society meeting

Join us at the 18th International Conference of the Metabolomics Society Meeting. We’ll have a Compound Discoverer Workshop on Sunday, 19 June 2022 | 09:00 – 11:00 [CEST] at the Sercotel Sorolla Palace. You can sign up for the workshop here.

Upcoming Webinar on May 17th : Probing Metabolite Utilization and Growth in Pathogenic Microbes

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.

Second Compound Discoverer™ Webinar Series 2021

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.


QF1 for Compound Discoverer 3.2

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.
