3.4 Capillary connections in the IC system
This chapter contains general information concerning the capillary con-
nections in the IC instruments and systems.
Generally speaking, capillary connections between two components of an
IC system are made up of one connection capillary and two pressure
screws with which the capillary is connected to the respective compo-
nents.

1 PEEK pressure screw (6.2744.014)
Use on the injection valve. 2 Connection capillary
3 PEEK pressure screw, short
(6.2744.070)
For use on the high pressure pump, the
purge valve, the inline filter, the pulsation
absorber, the guard column and the separa-
tion column. 4 PEEK pressure screw, long
(6.2744.090)
Use on special components. Is not used on
all instruments.
Note
In order to keep the dead volume as low as possible, capillary connec-
tions should generally be as short as possible.
Note
For an improved overview, capillary and tubing connections can be
bundled with the 6.1815.010 spiral band.
