WebA specific m/z value and also the method like 10% valley or 50% valley or full width at half maximum ( FWHM) must be given. Resolving power is usually a large number (up to 2,000,000 for FT-MS) and is used as “performance” parameter. Mass Resolution usually refers to the ability of separating two narrow mass spectral peaks. WebMass. Spectrom. 10, 1819-1823). Basically, ICR frequency is proportional to B, so as B increases, all of the ICR frequencies also increase, as does the DIFFERENCE between any two ICR frequencies. That's why resolving power is proportional to B. The magnet also serves to confine ions in a plane perpendicular to B at the most homogeneous spot ... WebMar 17, 2024 · Location.
