Abstract
Sensitivity enhancement by the use of inductively coupled milli- and microcoils has been demonstrated in solid-state as well as liquid-state NMR. In this work, we discuss the practical aspects of using inductively coupled solenoid coils of different sizes in a liquid-state NMR spectrometer. The sensitivity and resolution enhancements from these resonant coils, with sizes ranging between 3.0 and 0.75 mm i.d., are measured for 23Na single-pulse and multidimensional imaging experiments and compared to the results obtained with the conventional liquids NMR 5.0-mm saddle coil. Enhancements in voxel-based sensitivity (SNR per ?scans) were measured in multidimensional MR images and were found to be as large as 20.4 with the 0.75-mm coil.
