Abstract:
A dual-function nuclear magnetic resonance probe comprising:a) a radio-frequency coil for applying radio-frequency energy to a sample; b) an upper insulator held in fixed position above said radio-frequency coil, said upper insulator having an upper longitudinal sample-holding aperture for sequentially centering a stationary-sample vessel and a flow cell in said radio-frequency coil, said upper aperture having a tapered guiding section for guiding said stationary-sample vessel from above through said upper insulator; c) a lower insulator held in fixed position below said coil, said lower insulator having a lower longitudinal sample-holding aperture aligned with said upper sample-holding aperture, for centering said flow cell within said radio-frequency coil; and d) a guide tube held in fixed position below said lower insulator, for guiding said flow cell from below through said lower sample-holding aperture.
