3. Maintaining pressure, screw the blue nut connector clockwise with your other hand until
the tubing is secured (Figure 59).
Figure 59 Securing tubing to the upper port of the flow cell
The connector should be initially hand screwed onto the flow cell until finger-tight. Then
apply an additional tightening of 1/8 of a turn using the 5.5 mm wrench supplied
(part number 09923411).
4. Repeat Step 1–3 to connect the tubing from the injection station to the lower port of
the flow cell.
5. Place the flow cell into the shuttle.
The shuttle hinged arm should be open (pushed back) and the securing clip should be
open and lifted up.
6. Rotate the shuttle hinged arm back into place, feeding the tubing into their respective
grooves in the liquid presence sensor as you do so.
7. Ensure that the tubing to the injection station is sited correctly in the lower groove, and
that the tubing to the FCM is sited correctly in the upper grove.
Refer to Figure 54.
8. Close the catch, ensure that the tubing is not stretched or crimped, and then secure the
screw.
CAUTION
Ensure that no tubing or cabling is loose on or around the sample
shuttle or spectrometer on the open side towards the autosampler. This
is to avoid damage to the system during movement of the autosampler
arm or the sample shuttle.
9. If you are replacing the lower flow cell on a DUO system, then replace the sample
shuttle and push the stacking system back onto the connections at the FCM.
10. Reconnect the tubing from the lower port of the flow cell to the connection at the
injection station.
11. Reconnect the tubing from the upper port of the flow cell to the connection at the FCM.
