DP/SP Routine Maintenance
This section describes routine maintenance procedures for the ICS-3000 Dual
Pump (DP) or ICS-3000 Single Pump (SP) that users may perform. All other
maintenance procedures must be performed by Dionex personnel.
7.2 DP/SP Daily Maintenance
• Check for leaks at the following locations: the eluent proportioning valves
(gradient pump only), vacuum degas chambers, and eluent reservoirs. Tighten
or replace any leaking fittings.
• Wipe up liquid spills and rinse dried reagents off pump components with
deionized water. Dry the leak sensor thoroughly; if the sensor is not dry, it will
remain activated and continue to report a leak to the Audit Trail.
• Check the liquid level in each eluent reservoir and refill as required.
• Check the liquid level in the seal wash reservoir. The liquid level should
remain between the Min. and Max. markers on the reservoir label.
• Rinse each eluent reservoir thoroughly (inside and out) with ASTM filtered,
Type I (18 megohm-cm) deionized water and dry with clean, particulate-free
air. If a reservoir still appears dirty, or if there is a slimy film on the interior,
clean the reservoir as instructed in Section 9.2
.
7.3 DP/SP Weekly Maintenance
• The end-line filters (P/N 045987) on the eluent lines may need to be replaced
weekly, depending on water quality and eluent conditions. For example,
replace the filters weekly when using an EluGen cartridge to generate
carbonate/bicarbonate eluent.
When the end-line filters are new, they are pure white. Replace the filters
whenever they become discolored, if bacterial buildup is evident, or if eluent
flow is blocked.
NOTE It is especially important to regularly replace end-line
filters when using aqueous eluents. Aqueous eluents may
contaminate the filters with bacteria or algae; although
the contamination may not be visible, it can cause flow
restrictions to the pump.
