2.3 Description of the connections
2.3.1 Connection of capillaries/tubing
The connections for eluent, sample and regenerant consist of:
• PEEK capillaries 6.1831.010 (inner diameter = 0.25 mm)
• PTFE microcapillaries 6.1803.030 (inner diameter = 0.5 mm)
• PTFE tubing connections to the MPaks 6.1837.000 (inner di-
ameter = 1.5 mm)
The PEEK capillaries and PTFE microcapillaries can be connected ei-
ther with PEEK pressure screws 50 6.2744.010 (long) or PEEK
pressure screws 51 6.2744.070 (short, for connection to the IC
pump).
The "PTFE tubing connection to the MPak" 23 can be connected to the
PEEK pressure screw 52 4.422.4510 (wide).
The connectors must be fitted to the capillaries as follows in this case:
Capillaries provided with new connectors must feature a flawless, flat
cut edge. In order to ensure this, it is best to use the tubing cutter
6.2621.080.
1 Fit pressure screw
Slide the corresponding pressure screw (50, 51 or 52), as
shown in Figure 4 onto the capillary 53 (23 for MPak connec-
tion).
2 Insert the capillary into the connection
Slide the end of the capillary fully into the corresponding
connector (in order to avoid dead volume).
3 Tighten the pressure screw
Firmly tighten the pressure screw (50, 51 or 52) by hand (do not
use tools).
