LC-MS/MS Query

LC-MS/MS Query uses MS1 data (Parent Ion m/z) and MS2 data (Fragment Ions m/z and Intensity values) entered by researchers, to search against either the experimental spectral library (default, both public experimental spectrum library and species-specific experimental spectrum library), or both the experimental spectral library and the in silico spectral library (check select box). It returns all matched reference metabolites for the paired MS1/MS2 data of your interest.
