A comparison of different pulse sequences in the nondestructive estimation of seed oil by pulsed nuclear magnetic resonance technique

Three basic pulse sequences,viz., Free Induction Decay (FID), Spin Echo (SE) and Carr-Purcell-Meiboom-Gill (CPMG), available in the pulsed nuclear magnetic resonance technique have been used to estimate the relative oil content in single as well as bulk samples of oil-bearing seeds. Conclusive evidence has been presented to show that the CPMG sequence is vastly superior to the other two as far as the effects of seed orientation and moisture content are concerned.
