Turbo Pump
The 7000 Series Triple Quad has one turbo pump.
The turbo pump chambers have screens to keep debris out of the pump. Pump
speed is controlled by the turbo controller.
Analyzer Chambers
The analyzer chambers (Figure 21) are located inside the vacuum manifold.
The manifold is extruded and machined from an aluminum alloy. Large
openings in the side, front, rear, and top of the manifold are closed by plates
and sealed by O-rings. Ports in the manifold and the plates provide attachment
points for the ion vacuum gauge, calibration valve, vent valve, collision cell,
GC/MS interface, and high-vacuum pump.
The turbo pump is bolted directly to the bottom of the manifold.
