Dionex ICS-1100 Ion Chromatography System
78 Doc. 065289-03 10/12
4.14 Baseline Noise or Drift
• Flow system leak; erratic baseline
Check all fittings and liquid lines for leaks. Tighten or, if necessary, replace
all liquid line connections. Refer to Installation of Dionex Liquid Line Fittings
(Document No. 031432) for tightening requirements. The manual is included
on the Thermo Scientific Reference Library DVD (P/N 053891).
• Trapped gases
Release any trapped gases in the cell by loosening the lines to and from the
cell and then retightening them. Also loosen and retighten the fittings to and
from the suppressor eluent ports.
• Pump not properly primed
Prime the pump (see Section 5.17
).
• Contaminated or incorrect eluent
Remake the eluent, using concentrated eluent and ASTM filtered, Type I (18-
megohm) deionized water.
RFIC-ER systems only: Replace the RFIC-ER columns, if necessary. An
Audit Trail message will inform you when a column is approaching the end of
its useful life span. You can also check the life expectancy of the columns on
the RFIC-ER Wellness panel.
• Rapid changes in ambient temperature
Make sure the ambient temperature is between 4 and 40 °C (40 and 104 °F).
Make sure air conditioning and heating vents are directed away from the
Dionex ICS-1100 and the Dionex ICS-1100 front door is closed.
• Insufficient system equilibration following changes to operating
parameters; especially apparent when operating at high sensitivities
Allow a longer system equilibration time (up to 2 hours) before starting
operation.
• Incorrect suppressor operating conditions
Refer to the suppressor manual for troubleshooting information. Suppressor
manuals are included on the Thermo Scientific Reference Library DVD
(P/N 053891).
