The 7200 Accurate-Mass Quadrupole Time-of-Flight GC/MS
System
The 7200 Accurate-Mass Quadrupole Time-of-Flight (Q-TOF)
GC/MS System is a standalone capillary GC detector for use
with the Agilent 7890A Series gas chromatograph. The 7200
Q-TOF features:
• Three turbomolecular vacuum pumps
• Rotary vane foreline pump
• Independently MS-heated EI or CI ion source
• Removable ion source (RIS) probe with RIS bayonet and
cooling chamber, which allows quick change from EI to CI ion
source with minimal loss of vacuum in the instrument
• Independently MS-heated hyperbolic quadrupole mass filter,
which can be heated to high temperatures, minimizing the
contamination typical with low temperature analyses
• Single hexapole collision cell
• Ion-focusing slicer
• Vacuum-insulated flight tube with dual-stage ion mirror
• Fast electronics, allowing fast sampling rates
• Analog to digital detector
• Independently GC-heated GC/MS interface with automatic
retraction during ion source removal
Physical description
The 7200 Q-TOF GC/MS is approximately 48 cm high, 71 cm
wide, and 89 cm deep excluding the flight tube and RIS handle.
The flight tube extends 84 cm up over the top of the instrument.
The RIS handle, when attached, extends 48 cm from the front of
the instrument.
The weight of the instrument is 152 kg for the mainframe. The
attached foreline (roughing) pump weighs an additional 11 kg.
