Whether the bulbed capillary external referencing method developed with an electromagnet NMR instrument can be performed also with a superconducting magnet instrument by only changing gcy from 2π/3 to 0 is studied. As the result, the same bulbed capillary and procedures giving high precisions and accuracies are found to be applicable to either electromagnet or superconducting magnet instrument and to either 1H or even 13C spectra. Thus, the validity of the generalized bulbed capillary theories and the superiorities of the bulbed capillary method over previous referencing methods are made clear.
