The following topics describe the components of the API source interface:

Except for the atmospheric pressure side of the spray cone and the nose cone of the ion transfer tube that is within the API source, the API source interface components are located in a vacuum chamber.

The following figure shows a cross-section schematic of the API source interface for the TSQ Altis Plus and TSQ Altis instruments. The API source interface for the TSQ Quantiva MS is similar to this source.
