Why can't we have an NMR in a plane?

Via the chemistry Reddit, is that really a mass spec in a NASA plane? (Looks like it is possible, and here's a similar picture?)

I get the sense that no one's mounted a NMR in a plane or a boat or a car. Too bad.

UPDATE: Thanks to bad wolf, I see that underground NMR for oil wells is real. Also, check out this company that actually sells NMRs to analyze groundwater. Of all the places where I expected to find NMR, underground was not one of them.

UPDATE 2: In the comments, examples of NMR in cars and proposals for NMR in space!

  1. maybe they can have the sample spinner connected by belt transmission to the turboprop engine, 20Hz = 1200 rpm (I am so tired of the hisss!)

  2. There are permanent-magnet-based benchtop instruments that should be operable on a plane or a ship, but I doubt that NMR is sensitive enough for atmospheric analysis at ANY magnetic field, let alone with a magnet that tolerates vibration and gross orientation changes and is light enough to get off the ground.

  3. When i worked at an oil company i learned geologists have NMRs that are mounted at the end of bores and lowered into drill holes. They are (or were) only ~2MHz but the T1 measurements told them useful info, as i recall.

    Putting the MS directly on the plane makes as much sense as the "go up, collect a sample of atmosphere and bring it back to earth to analyze" that the atmospheric chem groups do, or did.

  4. First line from a 24-year old abstract "Using a novel aircraft-borne automatic mass spectrometer, the odd-nitrogen gases NO, NO2, HNO2 and HNO3 were for the first time measured in a young exhaust-trail of a jetliner at cruise-altitude." Geophysical Review Letters, Volume 19, Issue 24, 24 December 1992, Pages 2421–2424 .

  5. In 2012 the Overland High School HUNCH team from Aurora, CO, used the Thermo Scientific™ picoSpin™ 45 NMR spectrometer to conduct the world’s first nuclear magnetic resonance (NMR) experiments in a moving automobile, in an in-flight aircraft, and in zero-gravity.

  6. Astronauts may soon have a portable MRI machine to keep an eye on their muscles and bones during a spell on the International Space Station. The custom-built, lightweight MRI should be ready to fly by 2016.

    1. NMR on Titan - I bow to your excellent Googling skills!

    2. Not quite Google, just following the field

      here is even better yet:
      http://investor.northropgrumman.com/phoenix.zhtml?c=112386&p=irol-newsArticle_print&ID=1937646

      apparently this NMR is to be mounted on satellites, rocket launchers & missiles and likes

      here is more about NMR gyroscopes

  8. Here I found the last one which I came across awhile ago I wanted to show

    Miniature Force-Detected NMR Spectrometer for In-Situ Chemical and
    Mineral Characterization
    http://www.lpi.usra.edu/meetings/LPSC99/pdf/1453.pdf

    pretty cool! also for NASA and deep-space

    All the best

  9. There is also the NMR-mouse and other single-sided NMR instruments:

    https://www.bruker.com/products/mr/td-nmr/minispec-profiler/single-sided-nmr/overview.html

    They may not give you your typical 1H or 13C spectrum, but you can do relaxation measurements to get an idea of sample quality. The lecture I saw on the NMR-Mouse suggested applications in tire manufacturing - using relaxation measurements as a quality check to ensure rubber homogeneity.

  10. Wait until Hollywood releases the film NMRs on a Plane.

    1. You have to watch out for those NMR bites...

  13. Saw a mass spec on board a Russian marine natural products research vessel in Sydney in the 90s. The had hplc, columns out the wazoo, mass spec, uv, ir, but no NMR. Oh and a complete mouse animal house on the lowest deck
