    AbstractHigh-field asymmetric waveform ion mobility spectrometry (FAIMS) is a gas-phase separation technique which, when coupled with liquid chromatography tandem mass spectrometry, offers benefits for analysis of complex proteomics samples such as those encountered in phosphoproteomics experiments. Results from LC-FAIMS-MS/MS are typically complementary, in terms of proteome coverage and isomer identification, to those obtained by use of solution-phase separation methods, such as prefractionation with strong cation-exchange chromatography. Here, we describe the protocol for large-scale phosphorylation analysis by LC-FAIMS-MS/MS.
