Peptide Identification & Structural Elucidation Without Tandem MS Peptide Identification & Structural Elucidation Without Tandem MSUltraFAIMS provides a lower cost alternative to tandem mass spectrometry for experiments that require precursor selection prior to fragmentation by collision induced dissociation (CID). FAIMS-in source CID-MS (FISCID-MS) can be used in conjunction with liquid chromatography and will be of particular interest to those carrying out proteomic analysis of complex biological samples.
