5.5.4 If Eluent Packs Are Incorrectly Attached
If you attach the bottle cap (with nozzle) of one eluent to the wrong type of eluent pack, clean the nozzle and chamber
inside the instrument, then attach the bottle cap correctly. Eluents A, B and CV differ in composition, therefore,
changing nozzles without first cleaning them will cause mixing of eluents, producing inaccurate measurement results.
Prepare: Cap for eluent pack (that was originally on the pack before opening) and gauze
1 Clean the eluent nozzle.
a Lay out gauze near the instrument.
b Remove the eluent pack with the wrong nozzle attached from the
bottle tray.
c Remove the bottle cap with nozzle from the pack.
d Wipe any liquid from the nozzle with a new piece of gauze.
• Place the nozzle on the gauze.
e Attach the cap (that was originally on the pack before opening) to
the pack, and tighten it securely.
2 Drain eluent from the chamber.
a On the standby screen, touch , <7. Maintenance menu> and <5. Drain menu> in that order.
b On the [Drain menu] screen, select the eluent whose nozzle was
inserted into the wrong pack.
• Fluid is drained from the chamber.
• After completion, the [Drain menu] screen will appear again.
c Touch to return to the standby screen.
NOTE:
Detaching the chamber without first draining eluent may spill eluent and damage the instrument. Be sure to
drain fluid before removing the chamber.
REFERENCE:
Repeat from step 1-a if the nozzle of other eluents was also
wrongly inserted.
