Abstract:
An NMR apparatus, comprising:an NMR transmitter for transmitting one or more signals to a number of samples; a number of sample holders each operable to receive a corresponding one of the samples for NMR analysis; a plurality of detection coils each operable to detect a an individual response of a corresponding one of the samples to one or more signals from said NMR transmitter; an adjustable magnetic field source proximate to a sample space arranged to receive said sample holders, said magnetic field source being operable to selectively provide: a first magnetic field to generate a first collective response of the samples when received in said sample space and excited by said one or more signals from said NMR transmitter, a second magnetic field having a gradient relative to said first magnetic field to generate a second collective response of the samples when received in said sample space and excited by said one or more signals from said NMR transmitter, said second collective response corresponding to a number of different frequency shifts relative to said first collective response, said different frequency shifts of said second collective response each corresponding to a different one of the samples; and a processor operable to determine a number of spectral characterizations as a function of said first collective sample response and said second collective sample response, the spectral characterizations each being representative of a different one of the samples.
