Aligned nuclear magnetic resonance results

A non-transitory computer readable medium for generating aligned nuclear magnetic resonance (NMR) results from a group of NMR units, the non-transitory computer readable medium stores instructions executable by a processor for:

• obtaining, for each NMR unit of the group, an NMR spectrum of a fluid sample, the NMR spectrum of the fluid sample being generated using a permanent magnet of the NMR unit;
• determining, for each NMR unit of the group, a filter that converts the NMR spectrum of the fluid sample to a lowest resolution NMR spectrum generated by a lowest resolution NMR unit of the group;
• wherein the filters preserves a value of at least one integral associated with at least one NMR spectrum unit line;
• wherein a filter of a given NMR unit of the group is calculated based on (i) a NMR spectrum line shape of a sample of a fluid of a known content obtained from the lowest resolution NME unit, and (ii) a lowest resolution NMR spectrum of the fluid sample;
• generating a group of aligned NMR spectrums by applying, for each NMR unit of the group other than the lowest resolution NMR unit, the filter of the NMR unit on the NMR spectrum of the fluid sample;
• and
• applying a model on the group of aligned NMR spectrums to provide aligned results indicative of a content of the fluid samples evaluated by the MNR units of the group.
