The new Overlap Evaluator ipad app. from Hiden Analytical is a reference tool for users of mass spectrometers operating in the fields of vacuum science and vacuum processing, and for advanced researchers using real time gas analysis systems. The evaluator enables the user to create a mass spectral overview of multiple fragmentation spectra to identify the mass peaks with least spectral interference and therefore most suited to species monitoring, and includes a quick mass peak look up table from a library of common gas and vapour species.
Based on the successful Hiden QGA quantitative gas analysis system software, up to 16 gas and vapour species can be added to an analysis ‘setup’. On adding the gases and vapours of interest, the MS overlap evaluator automatically provides a simulated analysis and displays the unique mass peaks together with any spectral overlaps. A spectral viewer is included to provide a histogram display of the simulated spectrum of the selected analysis.
The concentration levels for each component in the simulation mix can be adjusted, to provide a representative simulated mass spectrum of the users selected gas and vapour mixture.
The MS spectral overlap evaluator is available free to download from the Apple app. store.
