Claim 10:
11. A kit for a Nuclear Magnetic Resonance (NMR) system to measure two (2) different nuclei of a solid sample comprising:
(a) a solid sample NMR probe comprising:
a parent coil circuit;
a parent coil (210) having an inductance L2;
a capacitor (220) selected based on one or more of a NMR instrument, the solid sample NMR probe, and the solid sample to be analyzed;
a holder comprising a long axis, where the holder is adapted to insert the solid sample, where the holder is adapted to contain the solid sample;
a stator comprising a main axis, where the stator is adapted to hold the solid sample at a fixed angle relative to a magnetic field of the NMR instrument, where the stator is adapted to spin the holder and the solid sample, where the main axis of the stator is at the fixed angle;
an idler coil circuit;
an idler coil (211) having an inductance L1, where the idler coil (211) is adapted to be located in a fixed position relative to the parent coil (210), where the fixed position allows the idler coil (211) to be inductively coupled to the parent coil (210) such that the RF field symmetry of the parent coil (210) is minimally affected by the position of the idler coil (211);
a variable capacitor (221); and
a means of adjusting the variable capacitor (221) to observe a tuned condition between the parent coil (210) and the idler coil (211) such that a S11 plot of two closely spaced nuclei are matched to a minimal reflective power, where a Circuit Fill Factor (CFF) of the two closely spaced nuclei are approximately equal at the tuned condition; and

(b) instructions for using the solid sample NMR probe.
