High-resolution mass spectrometry
Sufficient resolving power to distinguish species differing by a small fraction of a dalton. Required to exclude 1 and 2 Da alternatives.
Related terms
- Unit resolution
- Resolving power sufficient to separate masses one dalton apart but not to determine exact mass. Cannot exclude a +1 or +2 Da alternative species.
- Resolving power
- A mass spectrometer's ability to separate two close masses, expressed as m/Δm. A quadrupole gives ~1,000; a TOF 20,000–50,000.
