Key Features

• Create and manage custom in-silico lipid spectral libraries
• Model complex lipid MS/MS fragmentation using intuitive fragmentation templates
• Generate high-confidence MS/MS lipid identifications
• Annotate chromatographic peak tables with lipid identifications
• Automatically filter peak tables for adduct peaks, in-source fragments, and dimers
  
  

Getting Started
