摘要
Fourier transform ion cyclotron resonance mass spectrometry (Fourier Transform Ion Cyclotron Resonance Mass Spectrometer; FT-ICR MS) is , the ionization source for generating ions; The ionized ions are dispersed over the space created by the source is incident , a reduction lens for reducing the distance between the ion by the deceleration of the incident ion and optionally ; And may include an ion cyclotron resonance cell to which the ions are incident through the deceleration lens . Using a deceleration lens inhibit the spread according to the mass of the ions , and can be expanded to mass measurement area can be measured at a time, to focus the ions , the ions can also be effectively incident on the ICR cell , so improving the measurement sensitivity .
