Site Preparation
Space and Weight Requirements
Table 2 lists dimension and weight i nformation for the MSD and related
components. Your site must have enough bench space for the MSD, GC, data
system, and accessories (Figure 1). In addition, there must be sufficient space
around the system for ventilation and maintenance access. At least 30 cm
(12 inches) to the left of the MSD and at least 20 cm (8 1/4 inches) behind the
MSD must be kept clear.
Benches must be sturdy enough to support the weight of the entire syst em.
The foreline pump can be located on the laboratory bench or on the floor. It
must be close to the MSD because it is connected by a 200-cm (79-inch) hose.
The hose is stiff and cannot be bent sh arply.
CAUTION Do not put the foreline pump on your laboratory bench if vibration-sensitive equipment

is located on the bench.
