Abstract
A mass spectrometer comprising: a multi-reflecting time of flight (MRTOF) mass analyser or mass separator having two gridless ion mirrorsthat are elongated in a first dimension (Z-dimension) and configured to reflect ions multiple times in a second orthogonal dimension (X-dimension) as the ions travel in the first dimension; the spectrometer configured to operate in: (i) a first mode for ions having a first rate of interaction with background gas molecules in the mass analyser or separator, such that the ions are reflected a first number of times between the ion mirrors; and (ii) a second mode for ions having a second, higher rate of interaction with background gas molecules in the mass analyser or separator, such that ions are reflected a second, lower number of times between the ion mirrors
