<p>A multi-turn Time of Flight mass analyser comprising a first electric sector, a second electric sector, one or more detector plates and a Fourier Transform analysis means. The second electric sector is arranged orthogonal to the first electric sector. Ions passing the one or more detector plates cause charge to be induced on to the one or more detector plates. The Fourier Transform analysis means determines the time of flight of ions per cycle or orbit of the mass analyser.</p> |
