Validation Strategies for NMR Probes in Field Measurement Applications

Saikat Sengupta¹, John C. Gore¹, E. Brian Welch¹

Nuclear magnetic resonance probes can provide real time, location specific, measurements of signal phase and magnitude. Here, we propose and demonstrate three different approaches to test the performance of NMR probes in the scanner. The approaches are, (a) motion simulation (b) spectrometer frequency offsets and (c) higher order field perturbations using a real time shim-switching module. Real time probe data is shown to encode each of these different perturbations faithfully, thereby demonstrating strategies for testing the performance and characterization of the probes against known and calibrated inputs.
