Gregory, The FDA in Cincinnati wrote a poster comparing EA-IRMS to the Picarro CRDS for detection of honey adulteration. There is a bit here on method development as well: https://www.picarro.com/support/literature/a_comparison_of_irms_and_crds_for_the_detection_of_economic_adulteration_of We also have a few app notes on using an EA with a CRDS for honey adulteration: https://www.picarro.com/support/library/documents/an022_combustion_modulecrds_for_d13c_analysis_of_imported_honey_and https://www.picarro.com/support/library/documents/picarros_combustion_modulecrds_provides_excellent_data_using_the_approved One limitation on method – this will work for C4 adulterated samples such as those adulterated with Corn Syrup, but unfortunately won’t effective with those using sugars such as rice syrup.

We never had any issues with viscous liquids such as these dribbling out of the tin cups. If you run lots of samples, you’ll want to keep an eye on your water trap.
