The invention provides for a magnetic field probe ( 100, 2202 ) comprising a container ( 104, 702, 1400, 1500, 1600, 1700, 1800 ) with a hollow cavity ( 106, 602 ). The hollow cavity comprises a duct ( 110, 700 ) connecting the hollow cavity with an exterior surface ( 109, 702 ) of the container. The container further comprises metallization ( 108, 800 ) surrounding the duct on the exterior surface. The container further comprises a metallic plug ( 400, 1000 ). The metallic plug at least partially fills the duct. The metallic plug forms a seal ( 402, 1002 ) with the metallization. The magnetic field probe further comprises a sample ( 300, 900, 1608 ) comprising fluorine 19. The sample at least partially fills the hollow cavity. The magnetic field probe further comprises an antenna ( 102 ) adjacent to the container for manipulating the magnetic spins of the fluid sample and for receiving magnetic resonance signals from the fluid sample. |
