An NMR probe comprising an RF resonator 48 serves in a first mode for conventional sensitivity optimized studies of abundant samples at frequency ?0, and in a second mode for independent sensitivity optimized studies of micro sample quantities at frequency ?0 through use of a removeably insertable self-resonant micro-coil 50 within the RF resonator 48 and closely surrounding a micro sample, that is preferably independently removeably insertable within the micro-coil. The NMR probe exhibits an enhanced tuning range to resonate in its first mode and in the second mode to inductively couple to the self-resonant micro-coil 50 to induce self-resonance of the micro-coil 50 at ?0. |
