Detection of Honey Adulteration with FlashEA Elemental Analyzer and DELTA V Isotope Ratio Mass Spectrometer

Stable isotope analysis of honey, in order to detect adulteration, is in widespread use and requires an Elemental Analyzer coupled to a Thermo Scientific DELTA V Series Isotope Ratio MS (IRMS). The elemental analyzer is used to combust the carbon of the bulk honey, and of the protein fraction extracted from the honey, into CO₂ which is analyzed by the IRMS for the ¹³C/¹²C ratio.
