Problem Probable Cause Remedial Action
High noise level, pulsation
(Cont'd)
The lamp is too old. Replace the detector lamp
(

Detector Manual ).
The wavelength is wrong. Select an appropriate
wavelength.
The Step is too small
(for example, 0.1 sec.) Increase the Step
(for example, to 0.5 to 1 sec.)
When using acetonitrile, valve
problems may be observed,
indicated by increased pulsation. Replace the sapphire
cartridges (inlet and outlet
valve) by ceramics cartridges
(

page 128).
ISO-3100BM
The membrane in the pulse
damper is defective.
Contact Dionex Service.
Pressure pulsation or
inconstant pressure The solvent is not degassed
sufficiently. Degas the eluent.
The solvent is degraded. Use fresh solvent.
There are pressure fluctuations
from the pump.
Purge the pump (

page 54).
Check the compression
values for the pump and
perform the remedial actions
as suggested (

page 121).
There are air bubbles in the
system.

The inlet valve or outlet valve on
the working cylinder is dirty. Clean the inlet check valve
and/or outlet check valve.
Consider replacing the check
valve (

page 128).
After a maintenance procedure
(replacement of pump head,
piston, or piston seal) the pistons
are not in the appropriate position
for normal operation. Remove and reinstall the
pistons (

pages 135
and 137).
Depending on the pump type:
The static mixer or inline filter is
blocked.
Replace the static mixer
(

page 147) or inline filter
(

page 149 or 150).
With an LPG-3400BM and

replace the filter frit in the
inline filter instead
(
