<p>A method for improving sensitivity of a QIT by overcoming deleterious space charge effects on the collection of higher mass ions in a QIT by rejecting residual air gas ions during ionization and by rejecting other ions during ionization employing a 1/m/z weighting of the amplitude of each secular frequency, where m/z is the mass to charge ratio of the ions. <IMAGE></p> |
