CAUTION:USING HP 1100 WITH ESA COULARRAY ORCOULOCHEM III ELECTROCHEMICALDETECTORSIt has recently been reported that several CoulArray users have observed abnormalbackground currents while using the HP 1100 HPLC Pump.According to HP TechnicalSupport,the issue is due to metals leaching from the pump.The pump is not entirelymade from 316 stainless and that other grades are used in the construction.Metalleaching from the pump is a significant problem when used with electrochemicaldetectors.HP is aware of this situation and strongly recommends that the HP 1100 pumpmust be "broken in"overnight using mobile phase and then actively passivated before usewith any ECD.ESA recommends that HP 1100 users contact Mr.Terry Whitt at HP (1-800-424-9759)for the appropriate passivation procedure.ESA will not warranty any cells that are damaged by use with other manufacturers HPLCsystems that have not been properly prepared for use with ECD.If you have any questions,please contact the ESA Instrument Service Department at1-800-275-0102 or its representative.
