DC Routine Maintenance
This section describes routine maintenance procedures for the ICS-3000
Detector/Chromatography Module (DC) that users may perform. All other
maintenance procedures must be performed by Dionex personnel.
7.9 DC Daily Maintenance
• Check the DC components for leaks or spills. Wipe up spills. Isolate and
repair leaks (see Section 8.26
). Rinse off any dried eluent with ASTM filtered,
Type I (18 megohm-cm) deionized water.
• Check the waste container and empty as needed.
NOTE If you are using an electrochemical detector, also see the
special maintenance considerations that are described in
Section 4.1.2
.
7.10 DC Weekly Maintenance
• Check liquid lines for crimping or discoloration. Relocate any pinched lines.
Replace damaged lines.
• Check for excess condensation inside the DC. Condensation may build up
when the DC is operated in a highly humid environment and the majority of
the applications are run at cold temperatures. To remove condensation, run the
DC at its maximum temperature for at least 48 hours for a dual-zone DC, or
72 hours for a single-zone (shared) DC.
7.11 DC Periodic Maintenance
• Calibrate the CD cell (every 6 months).
• Inspect the door seal for signs of damage. A defective seal impairs the
performance of the instrument. If the seal is defective, contact Dionex
Technical Support.
