2.3.2 Connection of syringe and aspirating tubing
For manual filling of the sample loops 27 mounted on the injection
valves, the 6.2816.020 Syringe and the PTFE aspirating tubing 29 al-
ready screwed to the valve are needed. These accessories are
mounted or adjusted as follows:
1 Connect syringe
• Remove the plastic stopper from connection socket 3 on the
front side of the 861 Advanced Compact IC (see Figure 1).
• Push 6.2816.020 Syringe (without needle) as far as it will go
into connection socket 3.
2 Lead aspirating tubing to the outside
• Lead the PTFE aspirating tubing 29 connected to the injec-
tion valve 28 through one of the feedthroughs 4 to the out-
side.
2.3.3 Connection of the drain tube for the inner compartment
The 861 Advanced Compact IC has a connection at the front to which a
drain tube for discharged liquids in the inner compartment can be at-
tached. Proceed as follows:
1 Connect drain tube
• Mount 6.1816.020 Silicone tubing on connection nipple on
the lower right side.
2 Lead drain tube to collecting vessel
• Lead the other end of the drain tube to a suitable collecting
vessel and fix in place.
2.3.4 Connection of the drain tube for bottle rack
The 861 Advanced Compact IC has a connection at the rear to which a
drain tube for discharged liquids in the bottle rack can be attached.
Proceed as follows:
1 Connect drain tube
• Mount 6.1816.020 Silicone tubing on connection nipple 9
(see Figure 2).
2 Lead drain tube to collecting vessel
• Lead the other end of the drain tube to a suitable collecting
vessel and fix in place.
2.3.5 Connection of PEEK capillaries
For the connections between high-pressure pump and detector block
6.1831.010 PEEK capillaries (i.d. = 0.25 mm, o.d. = 1 /
16
" ) are used
which are connected using either 6.2744.010 PEEK compression fit-
tings (long) or 6.2744.070 PEEK compression fittings (short).
