MACE

MACE provides a curated repository of electron impact (EI) mass spectra to expand and complement commercial GC/MS spectral libraries such as NIST and WILEY for chemical ecology applications.

Key Features:

• Curated EI spectra collection: Contains electron impact (EI) mass spectra specifically curated for gas chromatography-mass spectrometry (GC/MS) analyses to support chemical identification.
• Complementary database to commercial libraries: Fills spectral gaps relative to commercial libraries such as NIST and WILEY to broaden the scope of compound identification.
• Text file format: Spectra are stored as text files for direct use with GC/MS data processing workflows and file-format–based integration.

Scientific Applications:

• Compound identification in chemical ecology: Improves identification accuracy of complex mixtures of organic compounds in ecological studies using GC/MS EI spectra.
• Support for rare or novel compounds: Provides reference spectra for compounds that are absent from commercial libraries, aiding characterization of newly discovered or rare compounds.
• Comparative analyses across ecosystems and samples: Enables cross-sample and cross-ecosystem spectral comparisons using curated EI mass spectra.

Methodology:

Spectra are stored as text files representing curated electron impact (EI) mass spectra for GC/MS applications.
