    FAQ: 


    Q: What is the magnetic strength in Tesla?

    A: We use very weak magnets, only 1 T, because DNP in liquids only works well with magnetic fields less than 1 T. In turn, DNP improves the signal-to-noise ratio for one-dimensional spectra by about 400 times, and almost 100,000 times for multidimensional spectra. Therefore, the sensitivity of 1D is approximately as if we were capturing spectra at 100 MHz, and the sensitivity of 2D+ is approximately as if we were capturing spectra at 400 MHz.

    Q: Can I get 1D spectra from Elegant NMR system?

    A: The ability of the Elegant NMR measuring system to automatically interpret heteronuclear DNP NMR spectra on an adaptive grid completely disrupts the status quo in which 7- and 8- dimensional DNP NMR spectra, having sparsity values less than 0.1%, are very difficult not only to interpret, but even to visualize.

    In the Elegant NMR system, such spectra are identified with reference to a huge database con-taining about 1.7 billion spatial molecular structures.

    7-8-dimensional spectra can be projected onto one-dimensional slices and then visualized. We will implement this approach in the expert mode of the Elegant NMR software for reference purposes.

    Q: Do we need to use external MW source for DNP?

    A: No, Elegant NMR System is equipped with internal DNP source according to recently patented technology US 10773092 B2.

    Q: Do you have HPLC/GCMS inside, or how you separate unknown mixtures?

    A: We do not separate molecules, we separate signals. In classical HPLC, for separation to occur, we need the substances to be separated to form complexes with a stationary phase and the energy of formation of such complexes is significantly different. It is often possible to find a stationary phase that would orientate the substances to be separated well, but would not separate these mixtures well enough, for instance, because of the insufficient number of theoretical plates. In our apparatus we do not separate substances, namely, we orient them differently. This orientation affects the two-dimensional NMR spectra and it is possible, without separation, to obtain slightly different HSQC or NOE spectra, and on the basis of their correlations, to get relative concentration and pure spectra of the substances themselves.
