Metabolite High Resolution MS/MS Spectral Library
For use with the X500R QTOF system powered by SCIEX OS
The Metabolite HR-MS/MS library contains the high resolution MS/MS spectra in positive and negative ion mode (where appropriate) comprising more than 432 compounds. The high resolution library is designed for library searching against high resolution product ion data generated on the TripleTOF series of instruments. The library is accessible through MasterView 1.1. This kit includes one Metabolite HR-MS/MS Spectral Library 1.0 DVD and a single 1 year expiring license. After the one year expiration, the license must be renewed to continue to have access to the library.
