Removing the Ion Sweep Cone and the Ion Transfer Tube
Because buffer salts or high concentrations of samples can cause blockages in the bore of the
ion transfer tube, you must clean it.
If pressure in the ion transfer tube and RF lens region (Source Pressure gauge) drops below
2 Torr (TSQ Altis) or 1 Torr (TSQ Quantis or TSQ Fortis), a blocked ion transfer tube is
probably the cause.
1. Turn off the liquid flow to the API source.
2. In the Tune application, place the MS in Standby mode.
3. In the Ion Source pane, set the Ion Transfer Tube Temperature and Vaporizer
Temperature to 50 °C or less and observe the readback temperatures.
4. Turn the system off.

CAUTION Hot surface. The external surface of the spray insert, API source housing,
and entry to the ion transfer tube can be hot enough to burn your skin. Allow the
parts to cool to room temperature (approximately 20 minutes) before you touch it.
