Faults, possible causes and solutions (sample injection)

Malfunction

Possible cause

Solution

Leak around the in-
jection port
(Flash mode)

Dried sample or particulate
matter interferes with syringe
fitting

Clean the injection port with
appropriate solvent or
remove particulate matter.

Defective injection port (Luer
fitting) adapter

Replace the injection port.

Solid loader leaking Loader hardware is not prop-

erly set up

Verify that the loader
hardware is set up correctly.

Leak around the
prep injection
valve/sample loop

Loose fitting

Find the loose fitting and
tighten it up.

8.5

Faults, possible causes and solutions (fraction collection)

Malfunction

Possible cause

Solution

Liquid not being col-
lected in fraction
tubes

Incorrect fraction collection
settings

Verify that fraction
collection information is set
properly.

Liquid not centered
in fraction tube

Fraction collector is not cali-
brated

Recalibrate the fraction
collector.

Fraction collector
(FC) arm does not
move

Fraction collector arm did not
home properly

Reset the Fraction collector
arm.

Fraction collector arm motor is
slipping

Tighten the motor coupler.

Fraction collector arm is ob-
structed

Check for cable or burr in
the fraction collector arm
path and remove any
obstruction.

Tray not detected

RFID tag is bad

Put another tray into the
same position to see if it is
recognized to confirm the
cause.

Replace RFID tag.
