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), or both the experimental spectral library and the in silico spectral library (check select box). It returns all matched reference compounds for the paired MS1/MS2 data of your interest.
