7. Secure the T20 screws near the center line of the module leading to the injector and
detector pneumatic network prior to tightening the captive screws which hold the
module. See
Figure 471 .

It will be necessary to push down on the right side of the module near the back edge to
ensure engagement of the 25 pin D-sub electrical connector. Wiggle the module as
necessary to engage the pins and then secure the screws.
8. At this point, the regulator that delivers the helium can be set to the appropriate pressure:
typically 110 psig (760 kPa; 7.6 bar) will suffice for 0.25 mm i.d. columns of 30 m
length.
Dial the pressure up slowly while tapping the pressure gauge in order to set the
appropriate pressure.
Table 20 serves as a guide for setting the correct helium regulator
pressure.
