An 16O2+ ion circulates at 500. MHz in an ICR cell.
i) What would the cyclotron
frequency be for an 14N2+ ion in this same cell under the same conditions, in MHz? Please use integer atomic weights as indicated. (Hint: take ratios of expressions for the cyclotron frequency, cancel like terms and rearrange.)
ii) What would the m/z ratio be for a singly charged ion that is circulating at one half the frequency of 16O2 + ?
iii) What would the cyclotron frequency be for a doubly charged ion, O22+?
iv) Suppose you were collecting data over a 0.2 second sampling interval, and your resolution were 10,000. How long would your data sampling interval need to be to increase the resolution to 25,000?
