The MS-omics pipeline. A sample is introduced to an ionization mechanism with or without a preliminary separation technique, where particles receive a charge enabling the detector to estimate the mass-to-charge ratio (m/z) and intensity of each analyte. If the system has tandem mass spec capabilities, some precursor ions (MS1) are selected for fragmentation (MS/MS). Data processing techniques prepare the data to be quantified via statistical methods and identified via matches to theoretical databases.
