A method for calibrating time-of-flight mass spectrometers is provided. The method includes at least modeling a time-of-flight mass spectrometer as a composite operator in accordance with a state space approach. The model is used to perform both symbolic and numeric propagation. To perform symbolic propagation, the model is used to derive closed form equations for the time- of- flight, by symbolically propagating the state of one or more ions modeled as state vectors. To perform numeric propagation, the model is used to calculat e the time-of-flight by numerically propagating the state vector representatio n of one or more ions.
