Abstract:
A flow-through NMR probe comprising:a lower insulator having a lower aperture;an upper insulator, supported at a distance above the lower insulator and having an upper aperture, the upper aperture aligned on a substantially vertical axis with the lower aperture;an upper insulator ring positioned in the upper aperture, having an inner diameter sufficient to slidably traverse an NMR flow tube and being keyed on top to fit a lower end of a removable connector;a lower insulator ring positioned in the lower aperture and having an inner diameter sufficient to slidably traverse an NMR flow;a guide tube having a first end and a second end, and an inner diameter sufficient to slidably traverse a spacer ring, the guide tube attached at the first end to the lower insulator for communicating through the lower aperture toward the upper aperture substantially along the vertical axis;a spacer ring slidably disposed in the guide tube below the lower insulator, the spacer ring having an inner diameter sufficient to tightly fit around an NMR flow tube;an NMR flow tube having an inlet end and an outlet end, the flow tube slidably disposed through the spacer ring, the first end of the guide tube, the lower aperture, the lower insulator ring, the upper aperture and the upper insulator ring, and substantially aligned along the vertical axis, the inlet end of the flow tube connected to an inflow tube; anda removable connector connecting the outlet end to an outflow tube, the lower end of the removable connector seated in the key in the top of the upper insulator ring.
