Application Note: apex®-Qe: A Powerful Platform for Molecular Formula Determination
19 October 2006

The ability of mass spectrometry to determine molecular composition is widely applicable to various disciplines including pharmaceutical discovery, metabolomics, petroleum analysis, geochemistry, and environmental chemistry, among others. Performing compositional analysis without fragmentation spectra is advantageous, allowing identification without analysis of complex fragmentation patterns, and is intrinsically faster allowing higher throughput. This application note demonstrates the effectiveness of composition analysis using the Generate Molecular Formula (GMF) tool on apex-Qe acquired small molecule data.
