elucidation becomes quite obvious. Unfortunately, the combination of NMR with chromatographic
systems is one of the most difficult tandem combinations to operate and, although significant advances
have been made over the past few years, much remains to be accomplished. For those requiring more
information on NMR, the books by Banwell and McCash (11) and Paudler (12) are strongly
recommended.
The NMR Spectrometer
The early NMR spectrometers operated at about 60 MHz and thus the necessary field of 14 kilogauss
could be produced by conventional iron cored electromagnets or even by ceramic permanent magnets.
