Figure 1 Recommended System Layout
The 24.5 kg (54 lb) mechanical pump belongs on the floor beneath the workbench on which the
Saturn system sits. To accommodate the pump, the workbench should be no higher than 91 cm
(36 in.); if you use a higher table, be sure to place a suitable stand or support under the table to
elevate the pump. If your bench adjoins a wall, you will either need to drill a 38 mm (1.5 in.)
diameter hole through the bench to accommodate the vacuum hose, or to place a suitable shelf
above and behind the Saturn GC/MS for the pump.
Power Requirements
You are responsible for providing two dedicated fourplex single-phase power sources with earth
grounds hard-wired to the main power panel ground. Within North America these power
sources must be 20A, 100-130 Vac, 60 Hz ±3 Hz, and outside North America they must be
10A, 200-260 Vac, 50 Hz ±3 Hz. One of these fourplex power sources is for the mass
spectrometer, computer, monitor; and printer the other fourplex power source is for the gas
chromatograph and (optional) 8200 AutoSampler. If you have additional sample preparation
devices or test equipment, we recommend a separate dedicated power source for their
operation.
Care must be taken to ensure that sources of radio frequency interference (RFI) and
electromagnetic interference (EMI) are not placed on the same power line, or share the same
ground plane, since this can degrade the performance of the GC. Equipment such as motors,
solenoids, fluorescent light fixtures, and radio communication transmitters should be isolated
from the instrument and connecting cables as much as possible.
The power cable from the GC is approximately 2m (6 ft) long and fitted with National Electronics
Manufacturers Association (NEMA) 5-20P power plugs. The NEMA 5-20P power plug and
corresponding outlet are shown in Figure 2(a). NEMA 5-20P plugs are rated at 20A and
120 Vac.
