The continuous gas-phase ion separation and atmospheric pressure focusing properties of high-field asymmetric waveform ion mobility spectrometry (FAIMS) offer significant advantages for the mass spectrometric analysis of tryptic digests of proteins. In this study, tryptic peptides of pig hemoglobin were examined by ESI-FAIMS-MS using a newly designed FAIMS(More)
Devices based on differential mobility spectrometry (DMS) are used in a number of ways, including applications as ion prefilters for API-MS systems, as detectors or selectors in hybrid instruments (GC-DMS, DMS-IMS), and in standalone systems for chemical detection and identification. DMS ion separation is based on the relative difference between high field(More)
