let me start sharing information about our technology.
It is well known that NMR devices require high stability of magnetic field and oscillators, the accuracy of said stability should be about several ppb (1.0e-9), otherwise spectra becomes blurred.
One of the biggest disadvantages of low-field NMR spectrometers is the high fluctuation of their magnetic fields. If the magnets are small (about the size of a portable device), the intensity of the external magnetic field and its direction may be adversely affected. Even turning a 1.5T NMR spectrometer to an angle about 6 degrees perpendicular to the earth\\\'s magnetic force lines will ruin the measurements, and the device will have to be recalibrated. Even a slight movement of the table on which a currently available spectrometer is placed may disturb the spectra significantly. Another related difficulty is that currently available spectrometers usually require high temperature stability (of the order of 0.01C), which is incompatible with chemical production equipment and in-situ measurements in chemical reactions.
The key idea behind our device is an experimental setup and data processing method that remove barriers of using instable magnetic field sources and standard oscillators. This idea is disclosed for everybody recently at https://arxiv.org/abs/1706.00237
There is a strong mathematical theory behind this idea, some part of this theory is also disclosed at https://arxiv.org/abs/1701.08544
some will be published soon.
