An acceleration voltage of 30.0 kV is used to accelerate ions into the 1.54 m flight tube of a time‑of‑flight (TOF) mass spectrometer. The frequency at which spectra can be recorded is dependent on how long it takes the slowest ion to travel from the source to the detector. If you wish to scan up to ?/?m/z 6801 at what frequency (spectra/s) could spectra be recorded if a new spectrum begins each time the slowest ion reaches the detector?
frequency:................spectra/s

An acceleration voltage of 30.00 kV is used to accelerate ions into the 1.657 m flight tube of a time-of-flight mass spectrometer. If two singly, positively-charged ions, one with a m/z of 5068.664 and one with a m/z of 5077.857, are accelerated at the same time into the flight tube, what will be the difference in the arrival time of the two ions at the detector? Enter the difference in arrival time as a positive value. Answer in ns.
Suppose that you have a time-of-flight mass spectrometer with a detector that can clearly resolve ion signs that are at least 14.0 nanoseconds apart in arrival time. Given a flight tube length of 1.40 m total field-free distance from source to detector, and a source with an acceleration voltage that extends over a 2.5 cm distance, a) determine the source voltage required to ensure that two proteins with masses 2237.5 amu and 2239.8 amu are adequately resolved, i.e. have a...
