Compare a measured spectrum
Paste peaks from an EPI spectrum, one per line as m/z intensity (tab, space, comma or colon). Compare against the selected entry, or search the whole library.
Score: cosine on square-root intensities, matched within the fragment tolerance (0 to 1). Use 0.5 Da for QTrap unit resolution.
No measured spectrum yet.
In-silico spectra. Intensities are predicted, not measured; reporter ions m/z 72.08, 58.07, 46.07 are not validated. Isomers share spectra, so use retention time to separate them.
