NMR Spectrometers

"Exactly how much fat is there in my kebab?"

NMR Spectroscopy is short for nuclear magnetic resonance spectroscopy. What it does is find out the physical and chemical properties of atoms or molecules. It’s most commonly used by chemists to study organic molecules and handle quality control by measuring the purity of samples. NMR can analyze mixtures that contain known compounds or figure out what kind of unknown compounds are found in substances.

Our NMR spectrometer solutions and equipment

Nanalysis specializes in NMR spectroscopes that are portable. The new model NMReady 60 is the first fully featured portable NMR spectrometer that does not require cryogens. We offer full shipping, installation, calibration and maintenance in Scandianavia and Baltic regions for all their products.

You may be thinking “Hmm. The last NMR apparatus I saw was big enough to have the chemists climb a ladder to a hatch for operation. It was HUGE. Can a portable model really work?” The answer: Yes! Although the NMReady 60 only weighs 25 kilograms, it houses all necessary magnets, electronics and a computer with large display interface.

These models are not meant to replace a high-field NMR spectrometer (that giant apparatus you might have seen before) fully, but there are many applications in which our products will do the job just fine:

  • Pharmaseutics
  • Biotechnology
  • Reaction monitoring
  • Polymer research
  • Biodiesel research
  • Teaching environments
  • Food sciences

How it works

Just like compass needles and other everyday magnets, the protons in atoms are tiny magnets. When you use a compass, the magnetic needle will always point north. If you take two similar magnets and put them close to each other, you’ll notice that the opposite ends attract. The end marked “N” for north, will want to stick to the end marked “S” for south on the other magnet. This is also why the compass needle points north. It’s attracted to earth’s magnetic south pole (which is the geographic north pole!).

If you try to move the compass needle with your hand, you can. The further you move the needle away from it’s preferred position, the more energy you have to use. As protons are magnets, they too point in certain directions. When you put a sample into a NMR spectrometer and introduce a magnetic field, the protons (magnets!) will react to the new magnetic field and change their “position”. This takes energy, which is taken from your newly introduced magnetic field! Your new field fluctuates, and you catch the fluctuation readings. This is where the “resonance” word in NMR comes from.
