Last year I was at Apimondia in Montréal, a big international convention of beekeepers, bee researchers, and suppliers of beekeeping and honey making equipment. One of the big events at Apimondia is the judging of honeys submitted from around the world. I walked by the exhibit area before the judging:

I was flabbergasted to see so many spots on the display shelves occupied not by jars of honey but by failure notices:
OK, what does "this exhibit has failed laboratory examination" mean? Well, it could be incompetence pure and simple - for instance, gathering honey from your hives before it has lost enough water will make it thin and more likely to spoil.
But in some cases it may mean that the honey was adulterated, diluted with corn syrup, full of banned chemicals like antibiotics or pesticides, etc. I was really shocked that so many honey producers would pay big bucks to ship their honey to Montréal, pay to enter it in the judging, and have it fail testing.

Atomic? Honey? Yes, this honey was tested on a Nuclear Magnetic Resonance (NMR) machine by TrueHoneyBuzz, a B.C. company started by two generations of learned beekeepers and businesspeople, Jerry Awram Ph.D and his son Peter Awram Ph.D.
The NMR machine is made by Bruker Scientific Instruments, and in spite of the alarming orbiting particles in the logo, it does not use any harmful radiation. In fact, one type of NMR machine is the MRI (magnetic resonance imaging) machines used in hospitals.
NMR uses something akin to a very low power microwave to stimulate molecules in the sample, which reveal themselves in peaks in the readout as the frequency is changed - just like turning the dial on an old-fashioned radio detects peaks at different frequencies - those are the radio stations.
Each kind of molecule has its own peaks, so the chemical composition of the sample can be found. Now, since a large proportion of "honey" in stores (up to 76% in the US , up to 20% of "pure" Australian honeys, and up to 50% of honeys imported from Asia) are in fact faked in various ways, North American beekeepers and honey packagers have been looking at cleverer and cleverer ways of detecting fakes.

Peter Awram got his Ph.D. at the University of British Columbia in microbiology, where he still does research as a member of the BeeHIVE Research Cluster. But he and his father have pioneered the use of NMR in Canada for honey testing. I got my very nice blackberry honey sample from their booth at Apimondia, where they had posters explaining their method, and the results of some internet detective work they'd done on providers of fake honey ingredients in China.
Want to learn how to make fake honey? Just go to youtube, as their poster showed:
