The API source interface for all the TSQ Series II mass spectrometers includes an RF lens and an exit lens (excluding the TSQ Fortis Plus and TSQ Fortis instruments).

Ions from the ion transfer tube pass through the RF lens and then the exit lens. The RF lens is an ion transmission device consisting of progressively spaced, stainless-steel electrodes. 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 multipole. The exit lens acts as a vacuum baffle between the higher-pressure API source interface region and the lower-pressure MP00 multipole region of the vacuum manifold.
