The excess of internal energy imparted to these metastable ions during ionisation is sufficient to give them a rate of decomposition such that the latter occurs during the ion flight-time.
As with metastable ions in a fragmentation process where [M.
An energy slit in the spectrometer also allows it to operate in a bandpass mode rather than a low-pass mode - low energy metastable ions
are rejected, leading to lower background counts and better detection limits.
