Screw outlet capillary 94
94 to coupling 96
96 using a 6.2744.010
Compression fitting.
•
Screw inlet capillary 82
82 of detector block 81

coupling 96
96.
6 Fix connection suppressor – detector block
•
Insert one of the column holders 84
84 (6.2027.030, 6.2027.040
or 6.2027.050) in mounting rail 83
83 and fasten coupling 96
96 in
the column holder.
7 Prepare 752 Pump Unit
•
Take two tubing cartridges out of the holder of the 752 Pump
Unit.
•
Lay a length of 6.1826.050 Pump tubing in each of the two
tubing cartridges and reinsert these in the holder without
kinking the pump tubing.
•
Regulate contact pressure on pump tubing in accordance
with the instructions printed on the pump.
Pump tubing is consumable material with a lifetime which depends on
the contact pressure. For this reason, raise the tubing cartridges
completely by loosening the clip on the right if the pump is switched
off for some considerable time (the set contact pressure remains
unchanged).
