2.8.4 Connection of the suppressor module
The three inlets and outlets numbered 1...3 on the suppressor module
47 each have 2 permanently mounted PTFE capillaries, which must be
connected as described as follows (see Fig. 16 and Fig. 18).
1 Inlet capillary for eluent
• Screw inlet capillary 96 marked with "Eluent" of suppressor
module 47 to outlet end of separating column 81 using a
6.2744.010 Compression fitting.
2 Outlet capillary for eluent
• Screw outlet capillary 97 marked with "Detector" of suppres-
sor module 47 to coupling 33 using a 6.2744.010 Compres-
sion fitting.
• Screw inlet capillary 45 of detector block 46 to other end of
coupling 33.
