The spray cone is an integral component of the API source interface cage. The ion transfer tube fits through a small orifice in the center of the spray cone. A graphitized Vespel™ seal acts as a seal between the spray cone and the back of the ion transfer tube’s nose cone.

The custom tool that you use to remove and install the ion transfer tube depends on whether the ion transfer tube is secured to the spray cone with a quarter-turn pin or a threaded fitting.

The following TSQ Series II mass spectrometers use an ion transfer tube that is secured with a quarter-turn pin:

  • TSQ Altis Plus
  • TSQ Altis
  • TSQ Quantiva
