Radial Induction Coil - Agilent Technologies 700 Series User Manual

Maintenance and Troubleshooting
For a uniform RF field, and to ensure the best performance from your
spectrometer, the torch should be positioned in the middle of the induction coil
and the coils should be uniformly spaced around the torch.
Check that the loops of the coil are aligned with respect to each other (running in
parallel) and that the turn-to-turn separation (the pitch) of neighboring loops lies
within the specified tolerance for your instrument type:
Radial induction coil (Agilent 715/725 ICP-OES radial instruments only)

Axial induction coil (Agilent 710/720 ICP-OES axial instruments only)

NOTE Pitch is measured from the center of one coil to the next, as shown above by the
arrows between the dotted gray lines, and not the gap between adjacent coils.
