Claim 1
Independent Claim
161 words
IN A NUCLEAR MAGNETIC RESONANCE SPECTROSCOPIC ANALYSIS METHOD WHEREIN NUCLEI OF HYDROGEN CONTAINED IN A LIQUID HYDROCARBON WHICH IS A PRODUCT OBTAINED FROM A TREATING ZONE COMPRISING A SAMPLE ARE POLARIZED IN A PRIMARY MAGNETIC FIELD OF POLARIZATION CROSSED AT RIGHT ANGLES BY A RADIO-FREQUENCY MAGNETIC FIELD OF PREDETERMINED FREQUENCY AND WHEREIN AT LEAST A PORTION OF THE RESONANCE BAND OF SAID NUCLEI OF SAID HYDROGEN IS SCANNED, SAID PRIMARY MAGNETIC FIELD BEING MODULATED WITH AN AUDIO-FREQUENCY MAGNETIC FIELD, THE IMPROVEMENT WHICH COMPRISES ADJUSTING THE FREQUENCY AND INTENSITY OF SAID AUTO-FREQUENCY MAGNETIC FIELD AND ADJUSTING THE RATE OF SCAN OF SAID RESONANCE BAND TO A VALUE SO AS TO BE ABLE TO OBTAIN A NUCLEAR MAGNETIC RESONANCE DISPERSION SIGNAL HAVING A SUBSTANTIALLY WHOLLY POSITIVE VALUE WITH RESPECT TO THE VALUE OUTSIDE THE RESONANCE BAND AND HAVING A SINGLE MINIMUM VALUE AT THE CENTER OF THE RESONANCE BAND OF SAID NUCLEI OF SAID HYDROGEN, INDUCTIVELY DETECTING A MAXIMUM INTENSITY OF THE DISPERSION
