7890 Series GC Site Preparation

GC, GC/MS, and ALS Site Preparation Guide 19

If using an ion trap MS:

The vacuum hose connecting the Ion Trap MS to the foreline pump is

200 cm (79 in) long. To accommodate the pump vacuum hose, the

bench should be no higher than 91 cm (3 ft). If your bench is higher,

place a bench that can support a 22 kg (48 lb) pump and isolate

vibration under the bench. If your bench abuts a wall, drill a 3.8 cm

(1.5 in) diameter hole through the rear of the bench for the vacuum

hose.

A 7890 Series GC shipping pallet for a GC is approximately 76 cm ×

86 cm × 10 cm (30 × 34 × 40.5 inches). For a 7890 Series GC with a thrid

detector, the pallet size is approximately 76 cm × 87 cm × 11 cm (30 × 34

× 42.5 inches).

CAUTION

The supporting surface for the 7200 Q-TOF GC/MS system should be kept relatively

vibration free. Do not put the rough pump on your laboratory bench with the 7200

Q-TOF GC/MS due to the vibration that the pump creates. Vibration can lead to a loss

of mass accuracy and resolution.

CAUTION

Make sure the 7200 Q-TOF GC/MS foreline pump is located where it is not likely to be

touched by operators.
