761 SD Compact IC / Instructions for Use 8.761.1043

2 Connection pump tubing - injection valve

• The sample is forced into the injection valve via the connec-

tion capillary 47.

• Detach the connection capillary 47 with the two pressure

screws 50 from the outlet of the injection valve and from the

opening in the door (it is fitted there only for delivery pur-

poses).

• Screw the ends of the connection capillary 47 to the inlet of

the injection valve and to the PEEK coupling 65 on the right-

hand end of the pump tubing (flow outlet) using one pressure

screw 50 (see Figure 11).

3 Connection injection valve - waste container

The connection capillary 48 routes the sample from the injection

valve into the waste:

• Connect the supplied PTFE capillary 6.1803.030 with a pres-

sure screw 50 6.2744.010 to the outlet of the injection valve.

• Route the other end at the rear out of the 761 SD Compact IC

into the waste container. Wait until after the rear panel has

been fitted to cut it to size (see Section 2.10).

The sample stream should be routed into a waste container down-

stream of the injection valve (see Section 2.8.2.).
