Topic: Current stage (June 2017)
Hi,

let me share with you some inside view of PCBs of the Elegant NMR Stick that we have developed and tested during last year. In the most cases we build only few just to perform experiments and we have working version incorporated into the spectrometer body, so that PCBs on the picture below was spare version and may not completely populated with some elements.

Topic: Electronic Datasheet and Parameters
Hi,

let me share current technical parameters of electronics inside the spectrometer.

We have:

1. two computational units,
1.1. one based on Cyclone 5 has 132 SIMD cores running at 160MHz with one MADD per core, i.e. ca. 40GFlop/s real performance,
1.2. dual Intel Atom 500MHz with 6GFlop/s peak performance that achieve ca. 1GFlop/s (we do not need more), with 4GB/90MB/s NAND and 1GB RAM,

2. clock with 90fs jitter and 2ppb stability on well conditioned temperature range (don\'t forg...
Topic: Small FAQ
Hi,

we expect to deliver first devices in about one month, hence, right now we are open for your kind pre-sales questions.

Dimensions

The Elegant NMR Stick is a small device. The probe has a diameter of one inch, a length of 10 inches, and a weight of about one pound. The upper PTFE part is suitable for standard NS29 ground glass joint - a standard chemical...
Topic: Ongoing development
Hi,

let me share with you our activity in this project and introduce my self.

Me, Ilgis Ibragimov, was involved in NMR signal processing since 1999. In the period since 1999 till 2008 I was mainly involved as mathematician collaborating with group of Vladislav Orekhov and Martin Billiter in Geteborg Sweden. In that time several important ideas were introduced, in particular, non-uniform sampling, sparse multi-dimensional decomposition, and model order reduction.

In 2008-2015 I was mainl...

Topic: Beta Tests and Experiments
Hi,

we are about to finish electronic development and fixing some electronic issues and send several beta to our kind beta testers. If everything goes well we expect to have beta spectra by the end of the June 2017.

Sincerely,

Topic: Magnetic FIeld Fluctuation Stability
Hi,

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 direc...
