The attachment flange (NW25 flange) for connecting the vacuum pump is at the spec-
trometer rear side. Figure 3 shows the valve block with removed cover.
The vent openings are covered by a plug made from sintered-powder metal which is air-
permeable (i.e. the spectrometer can be vented with the plugs installed on the vent
opening). (See figure 8.) The plug functions like a filter preventing particles from enter-
ing the spectrometer together with the influent air.
Note:
For detailed information about the vacuum pump refer to the user
manual provided by the vacuum pump manufacturer.
