3 Connection pump tubing – injection valve
• At the 733 IC Separation Center, loosen the rotary nipple
screwed onto the interior side of connection 22 22 or 28 28.
• Take PTFE suction tubing 84 84 (see Fig. 14 and Fig. 15 of the
732/733 Instructions for Use) completely out of connection 22 22
or 28 28 and unscrew from connection "1" of injection valve 66 66.
• Pull the PEEK capillary 18 18 through the opening 22 22 or 28 28 of
the 733 IC Separation Center and screw onto connection "1"
of injection valve 66 66 using a 6.2744.010 PEEK compression
fitting.
• Retighten rotary nipple on the interior side of connection 22 22
or 28 28 to fix the capillary 18 18.
4 Tubing connection injection valve – waste
• Insert 6.2744.020 coupling (from 733 accessories) into con-
nection 21 21 or 27 27 of the 733 IC Separation Center.
• Screw PTFE suction tubing 84 84 onto the 6.2744.020 coupling
attached to connection 21 21 or 27 27 and lead it into the waste
container.
In the case of the 733.0020 IC Separation Center with two injection
valves, it is possible to fill both sample loops from the same 766 IC
Sample Processor. For this, connection "1" of valve A (outlet of the
sample loop) must be connected to connection "2" of valve B (inlet of
the sample loop) using a 6.1803.040 PEEK capillary (15 cm).
