   Linked via "Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometers"

   Mass spectrometers are characterized by their resolution ($R$), defined as:
   $$R = \frac{t_{1/2}}{\Delta t}$$
   where $t_{1/2}$ is the mean time-of-flight (or center frequency) and $\Delta t$ is the width of the peak at half its height. High-resolution instruments, such as Orbitrap or Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometers, can achieve resolutions exceeding $100,000$, enabling the precise determination of elemental composition by resolv…
