Agilent Technologies G6600-90006 manual Pump Maintenance

Pump Maintenance

To maintain optimum performance of the Agilent 355 SCD and 255 NCD, routine replacement of the chemical trap (for ozone destruction), oil coalescing filter and oil (Edwards oil-sealed pump only) is necessary. Refer to Table 3 for the expected life span of each replacement part or material.

It is beneficial to keep a maintenance log that tracks when maintenance is performed and any instrument or operational changes that might impact performance. Also keep track of detector flow rates (oxidizer and hydrogen), pressures (burner controller and reaction cell in detector), and background signal (the difference between ozone “on” and ozone “off”).

Table 3 Operating Life of Components for Edwards RV5 Vacuum Pump

Component/Material	Operating life*
Chemical Trap (RV5)	~ 3 month
Oil Coalescing Filter (RV5)	~ 3 months
Pump oil†	~ 3 months

*The operating life is based on the total time logged during operation of the Detector with the Burner and the ozone generator ON.

†Pump oil can be purchased from a supplier or directly from Agilent: SAE 10W-30, Multiviscosity Synthetic Motor Oil such as, MOBIL 1 or AMSOIL.
