Chromatography Forum

Thanks to all of you who responded to the "levels of detection" question that I posted for a teen working on a 4-h project. He really appreciated all the responses.

One last question. He has seen several analyses and noted that most have the toxin measurements identified by ug/g, but there is one he saw with mg/kg. Are these basically measuring the same amounts? Also, is this measuring at ppm? (Sorry, I'm no help at all on this part, but when he's ready to rehearse his presentation when it's finished, I can really help then.)

Thanks!!
Joey

µg/g=mg/kg=ppm

DR,

Thank you so much. We were trying to think like someone smart, but were not sure if we were on track or not.

Thanks for confirming.
