T733 0-127 Sentence denotes While always important in drug design, sensitivity and resolution of NMR are two major factors that need special consideration.
T734 128-270 Sentence denotes Since both factors improve with increasing magnetic field strength, we have seen a spike in the demand for ultra-high-field NMR spectrometers.
T735 271-630 Sentence denotes Recently, 28.2 T (i.e., 1.2 GHz for 1H) magnets have become commercially available, and with recent advances in magnet technology, such as liquid helium recycling and magnetic field shielding [91], NMR has begun to offer far better resolution and higher sensitivity while reducing the substantial costs of maintaining the instruments compared to past decades.
T736 631-917 Sentence denotes Other steps have been taken to enhance the sensitivity of NMR including: the development of cryoprobes increasing the signal to noise ratio 3 to 4 times, and micro-coil probes that not only increased sensitivity but also reduced the amount of sample required for the measurements [445].
