Vacuum manifold (interior)
When CID is turned on, the collision cell chamber, inside the analyzer chamber, has a user
controlled argon pressure of between 1 and 4 mTorr. The forepump evacuates the argon in the
collision cell when CID is turned off.
Two removable side cover plates on the left side of the vacuum manifold allow access to the
Q0 ion optics, mass analyzer, and ion detection system. Two electrically conductive O-rings
provide a vacuum-tight seal between the side cover plates and the vacuum manifold.
