RF and Exit Lens
Ions from the ion transfer tube pass through the RF lens and then the exit lens ( Figure 10 ).
The RF lens is an ion transmission device consisting of progressively spaced, stainless-steel
electrodes. The TSQ Altis MS (
Figure 10 ) and TSQ Quantis MS ( Figure 11 ) have an RF and
an exit lens. The TSQ Fortis MS has just an exit lens ( Figure ). The MS applies an RF voltage
to the electrodes, and the adjacent electrodes have voltages of opposite phase. As the RF
amplitude increases, ions of progressively higher
m/z values pass through to the exit lens and
move toward the MP00 RF lens. The exit lens acts as a vacuum baffle between the higher
pressure API source interface region and the lower pressure MP00 RF lens region of the
vacuum manifold.
