RawBeans is a tool for performing quality control of proteomic mass spectrometry raw-data.
The tool integrates the ProteoWizard msconvert utility, thus it is vendor independent. 

The information it provides include: number of MS2 per file, Top N histogram, Charge State distribution, Injection Time histogram (for Orbitraps), retention time vs injection time, retention time vs topN, injection time vs intensity, total ion current, co-isolation in MS2, MS2 intensity, fragmentation efficiency, MS1 m/z distribution and chromatographic peak width.
