including all electronics
Beginning with its inception over 60 years ago, Nuclear Magnetic Resonance (NMR) technology has been a powerful method for investigating the chemical compositions of matter and even the atomic structure of molecules. Currently, conventional NMR spectrometers are large, expensive, and very complex to operate.
Our innovations in numerical algorithms and hardware design have made it possible to produce an easy-to-use, pocket-sized NMR spectrometer, which we call the Elegant NMR Stick.
Now, NMR technology is available for:
- universities and research institutions: for real-time monitoring of chemical synthesis
- the chemical industry: for real-time, in situ monitoring of chemical processes and reactions
- the oil and gas industry: for real-time droplet size and quality control
- the beer/wine/soft drinks industries: for real-time quality control
- the medical and pharmaceutical industry: for real-time, in situ quality control.
In addition to these uses, many other industrial facilities can profit from the use of a simple, robust, and affordable NMR spectrometer!
Elegant NMR Stick can work at temperatures up to 480℉/250℃
Suitable for nearly all chemical reactions, the Elegant NMR Stick provides real-time, in situ monitoring of key information for an advanced understanding and control of reactions without the need for extractive sampling.
The comprehensive nature of the data makes it especially useful for kinetic analyses. The elegant NMR Stick delivers in-depth reaction information, assisting organic chemists and scientists in their research and development of chemical compounds, synthetic chemical pathways, and chemical processes.
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.
To overcome these difficulties, we invented the following method: we should simultaneously perform measurements of at least two non-zero-spin isotopes with correlated oscillators:
Low-pass filter block that is used in parallel with all passed signals,
One or more sequentially-connected amplifiers,
A marker - a substance/mixture containing at least one non-zero-spin isotope with a priori known spectra and concentration - which is either:
- situated in the measured substance, or
- incorporated as the reference unit inside coils S.2, or
- incorporated in the walls of the measuring NMR camera;
One or several frequency generators and their signals, delayed on 1/4 period. Each frequency generator has fixed ratio (An/Bn) to the main frequency generator;
A set of mixer pairs with each mixer pair receiving an appropriate pair of signals and delivering their products.
A processing block that incorporates the method described at FIG. 1.
A block that continuously supplies pipeline data u
from S.7 into local storage and delivers it to processing block S.9.
A processing block that solves said minimization problem.
Ones this measurements occur, you may apply appropriate numerical algorithm and get out deviation of magnetic field and oscillators out of your measurements!

Additionally this fact opens possibility to perform 2D and multi-dimensional NMR spectra right out of this hardware and it is available by default from our hardware and software.

We expect to keep the price low for the Elegant NMR Stick with free software so it can be made available for every user and every scientist.
To do this, we request your kind support with advice, beta tests (only for customers that preordered 20+ Spectrometers), and preorders to be able
to finish the development of the Elegant NMR Stick and produce them in large quantities.
As of begin of 2018, we have already built and successfully tested several devices, and staying on bugfixing stage and solving problems with discontinued components.
Powering of device is over PoE! New picture will be available soon. PoE adapter is included.
Our warranty is 24 months from delivery day. The warranty is void in cases described in a datasheet chapter or in case of any mechanical/chemical/disassembly damage. We cannot provide a warranty for the strength of the magnet, because magnets can be demagnetized when placed in inappropriate conditions, e.g., near electromagnets or large iron parts. Our numerical method ensures that the device will work with different magnetic fields, so, if the magnetic field decays from 1.1 to 0.5 T, the Elegant NMR Stick will still collect data, but the measurement may take more time.
Based on our experience at normal conditions, the magnetic field decays very slowly, i.e., about 5-20% per year, so we do not expect that during first two years of usage you will have issues with the strength of the magnetic field.
New magnets may be ordered separately, or we may provide a refill of the magnets. Please, contact us for such cases.
Elegant Mathematics was found in 1991 in the USA, (Washington State), for development and manufacture of linear systems and eigenvalue solvers for vector-pipelined and massively-parallel algorithms, that was requested by the industry of the nineties in the last century, for the solution of mathematical, physical, chemical, aerodynamic and other tasks. Our experts worked on the newest computer facilities of that time: 32 processor vector-pipelined system Cray C90, massively-parallel computers Cray T3D-T3E with 1,024 processors installed in NASA, Cray Research Inc, and the University of Pittsburgh, on many massively-parallel clusters with IRIX, DEC, RS6000, HP, Convex processors in the Hawaiian High-Performance Center, and on a huge amount of Linux clusters worldwide.
In the beginning of the 21st century our company underwent significant changes. There came a new generation of employees, we adjusted to new industrial problems and entered the European market.
In 2006 Elegant Mathematics Ltd moved its activity to Germany where its head office is situated at the present. The staff of our company are highly qualified specialists, who received Master's and PhD degrees on graduating from the worldwide recognized universities. Our mathematicians, physicists, chemists and programmers search out new technologies and directions in the industry. The results of their research and development activities are regularly published in scientific journals, such as Nature, JACS, LAA, etc. Hence, you are assured to find the high standard of scientific knowledge at your disposal.
Since 2017 we reestabliched our US office (Elegant Mathematics LLC) to be closer to our US customers.
