Table II Resolution achievable by FTICR and Orbitrap mass spectrometers for various m/z values considering a 1 second acquisition time. 9.4 T field strength and two different Orbitrap analyzer designs (56, 62) are considered in these calculations. Please note that the values for FTICR are non-apodized while the values for Orbitrap are apodized.
