Induction Coil Maintenance - Agilent Technologies 700 Series User Manual

Maintenance and Troubleshooting
Perform a wavelength calibration.

Inspect the external gas supply system for leaks including the tubing

connected to the instrument. Replace any damaged, leaking or worn
components.

Induction Coil Maintenance

The induction coil transfers energy from the RF generator to the plasma. A
deformed coil will distribute the RF energy unevenly to the plasma and may cause
the torch or torch clamp to melt. If you suspect the coil has been damaged, you
should arrange a service call to replace the coil.
NOTE Due to the specialized expertise needed for the proper service of induction coils, it is
strongly recommended that the induction coil be serviced only by an Agilent field
service engineer. In addition to the safety hazards identified below, improper service
may cause performance degradation and may invalidate your warranty.
Fire Hazard
WARNING
Operating your Agilent ICP-OES instrument with a deformed induction coil could
cause the torch and/or torch lamp to overheat, which could create a risk of fire.
Failure to ensure the induction coil is properly maintained and positioned could
therefore result in personal injury or damage to the instruments and/or other
property.
Hot Surfaces
WARNING
The torch and torch compartment become extremely hot during instrument
operation and remain hot for some time after the plasma has been extinguished.
Allow the torch and torch compartment to cool for at least five minutes before
inspecting the induction coil. Wear heat-resistant gloves.
CAUTION
Take care not to touch the induction coil when installing torches or the snout
(Agilent 715/725 ICP-OES radial instruments only).
