Connect the end of the 6.2141.110 Cable marked with "732/1"

to the remote interface 24 of the 761 Compact IC (see Fig. 2).

2 Tubing connection 766 – injection valve

At the 761 Compact IC, loosen the rotary nipple 31 screwed

onto the interior side of connection 3 (see Fig. 3 and Fig. 4).

Take aspirating tubing 4 completely out of connection 3 and

unscrew from connection "1" of injection valve 32.

Cut PEEK capillary 18 installed at the 766 IC Sample Proces-

sor (see 766 Instructions for Use) to the desired length.

Pull the free end of PEEK capillary tubing 18 through the

opening of connection 3 of the 761 Compact IC and screw it

onto connection "1" of injection valve 32 with the help of a

6.2744.010 PEEK compression fitting.

Retighten rotary nipple 31 on the interior side of connection 3

to fix the capillary.

3 Tubing connection injection valve – waste

Insert 6.2744.020 Coupling (from 761 accessories) into

connection 3 of the 761 Compact IC.

Screw aspirating tubing 4 onto the 6.2744.020 Coupling and

lead it into the waste container.
