Bruker Ultra-High Resolution Qq-Time-of-Flight Impact II™
High Throughput Lipid Identification using Direct Infusion Mass Spectrometry Data from Bruker’s Ultra-High Resolution Qq-Time-of-Flight Impact II with SimLipid Software
Impact II - SimLipid workflow benefits from the following features:
- Import raw data directly from Bruker's native file formats namely, .baf, .yep, and .fid files.
- Visualize raw data, and results in a single workbench view – Total ion chromatogram, mass spectra, identified lipid species corresponding to each MS/MS spectrum, detailed lipid information and annotated MS and MS/MS spectra.
- Perform MS, and MS/MS lipid database search against SimLipid database containing 40, 312 lipid structures and 15,09,926 structure-specific in-silico MS/MS characteristic ions.
- Identify lipids from multiple experimental runs in batch mode - 20,000 MS/MS scans per batch.
- Perform database search for MS/MS scans by selecting multiple adduct ion species facilitating accurate identification of lipids from different categories.
- Filter lipid species based on specific class, or sub-classes.
- Ontology filters e.g., lipid species with even fatty acyls for profiling human whole blood samples.
- Distinguish isobaric lipids based on lipid-specific characteristic ions observed in MS/MS spectra using proximity score.
- Generate reports by exporting result to CSV, MS Excel, and HTML file formats, facilitating downstream statistical analysis.
