20 inserted in a cylindrical bore of magnet 16 and a control acquisition system 18 electrically connected to magnet 16 and probe 20 probe 20 includes one or more radio frequency rf coils 24 and associated electrical circuit components for simplicity the following discussion will focus on a single rf coil 24 although it is understood that a system may include other similar coils rf coil 24 and the various components connected to rf coil 24 form one or more nmr measurement circuits a sample vessel 22 is positioned within probe 20 for holding an nmr sample of interest within rf coil 24 while measurements are performed on the sample sample vessel 22 may be a sample tube or a flow cell to perform a measurement a sample is inserted into a measurement space defined within rf coil 24 magnet 16 applies a static magnetic field b 0 to the sample held within sample container 22 control acquisition system 18 comprises electronic components configured to apply desired radio frequency pulses to probe 20 and to acquire data indicative of the nuclear magnetic resonance properties of the samples within probe 20 rf coil 24 is used to apply radio frequency magnetic fields b 1 to the sample and or to measure the response of the sample to the applied magnetic fields the rf magnetic fields are perpendicular to the static magnetic field the same coil may be used for both applying an rf magnetic field and for measuring the sample response to the applied magnetic field alternatively.
