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)

Pitch of Radial Induction Coil
Figure 9.
Pitch measurement—a radial induction coil must have a pitch (
↕
) of
4.7 ±0.5 mm
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.
