Wed Aug 11, 4: Isomers cannot be differentiated from each other solely based on accurate mass measurement of the compound. If you increase the number of selected rules, you should also consider increasing the Maximum Number of Fragments Generated on Each Step as well. A local ChemSpider database installation is queried for structures based on mass. Other Links Mac Users:

Automated tracking of parent and generated metabolites during data analysis, at each time interval.
Wed Aug 11, 4: The software solution for efficient, comprehensive metabolite identification. Greater confidence in your studies with combined metabolite prediction and data-driven analysis for comprehensive metabolite coverage.
Please refer to the Frafmenter Start Guide.
From an in-house toxicology database of drug substances, 48 isomer groups comprising compounds, for which a reference standard was available, were found. You can try to increase the number of predicted fragments within the MS Fragmenter Options, or increase the number of fragmentation steps. Two software programs were used to characterize in silico mass fragmentation of compounds in order to identify characteristic fragments. MS Workbook Suite enables the creation of fully searchable databases of mass spectra, chromatograms, and UV spectra together with structures, assignments, annotations and other associated data.
Report results in both Excel and PDF formats, from the tabulated display window.

An array of capabilities for workflow automation, speeding up routine manual processing operations, automating migration of old data files, or populating fraggmenter databases with predicted properties. These compounds were either diastereomers or position isomers undergoing identical fragmentation.
Display posts from previous: It could be more helpful if ac software can guide me the possible fragmentation patterns. Discussions about chromatography data systems, LIMS, controllers, computer issues and related topics. In the Help window, use the tabs and the hyperlinks in the table to review the rules.
