Time-of-flight mass spectrometry (TOF-MS)

Mass analysis that derives mass-to-charge ratio from the time ions take to traverse a flight tube, often paired with ion mobility for high-speed, high-resolution proteomics.

Where it's used

Mass spectrometers for biopharma characterization
High-resolution and tandem mass spectrometers — Orbitrap, time-of-flight and triple-quadrupole platforms — that characterize protein identity, post-translational modifications, impurities and peptide biomarkers, from deep proteomics research through GxP biopharma release and clinical/forensic quantitation.
