BenchTop/PBM Mass Spectrometry Library Search System

Summary

BenchTop/PBM is a Windows-based library search system that performs computerized identification of mass spectral unknowns against reference libraries of mass spectra. It features a Probability Based Matching (PBM) algorithm that can perform sub-second searches of large databases (e.g. Wiley Registry), probability ranked match reliabilities, graphic display of chromatogram+MS data and search results, and graphic display of chemical structures. In addition, the BenchTop/PBM system contains a flexible parametric retrieval browser to query and view MS libraries.

Key Benefits

Description

The BenchTop/PBM Mass Spectrometry (MS) library search system is a reference library software that provides the powerful Probability Based Matching (PBM) search algorithm. Directly compatible with data from virtually any mass spectrometer (see Table 1), BenchTop/PBM search results are rapid, reliable and consistent, enabling BenchTop/PBM to perform an entire laboratory’s unknown analyses regardless of the different mass spectrometer data sources.

In addition to proven PBM identification capabilities, BenchTop/PBM includes a host of options to provide user flexibility for data viewing and manipulating, PBM search refinement, custom library maintenance and Reference file browsing/querying.

BenchTop/PBM MS Library Search System includes

Note: Mass Spectral reference libraries for use with BenchTop/PBM must be obtained sparately. For example, the Wiley libraries and NIST may be used, as well as customer user-supplied libraries.

Note: To those who are purchasing or have purchased the NIST MS database, note that NIST includes its own library browser and search software called the NIST MS Search software and AMDIS. The NIST MS Search software is somewhat comparable in functionality to BenchTop/PBM, though the data format compatibility in particular is less extensive. BenchTop/PBM is recommended primarily for those who are not using NIST or other search software or who have special needs with otherwise unsupported data formats.
