Today, firstly finished a "Preventive Maintenance" on the pump @ Agilen* 1100 system at Sept-08-2008. ( the fourth PM on the Agilen* LC system since 2004)
The system is working well, except a high frequency noise come from the Quan-Pump -> when the pump delivery mobile phase, the Sapphire Plunger forward and back -> a scratching noise from the pump.
-> found lots of dark matter in the pump, use the MeOH and H2O to wash ->
-> use the IPA to prime the LC system for 30 min. done!!!
Next step: should order the Preventive Maintenance kit and finish the PM task on the autosampler and VWD.
Note: some catalog #01018-68722, # G1311-68710.
