Is the smell worse with sunflower/grapeseed than with mct ?
It sound like the probe may be messing up with insaturated fatty acids, like spoiling the oil, promoting its oxidation. MCT normally gets only traces of omegas, but some references have enough to promote a bad smell when you oxidize it.
I have the distinct memory of a lab director ranting about how many days it took to clean up his hplc because #^>~**? MCT. It could be another hallucination
I found that back flushing my GC column every now and then helps ameliorate any build up.
At the time, I thought that it was perhaps not MCT, but that mystery oil that was suppose to kill people (what up with that story ?). Or perhaps it could be that strange low density MCT oil reffered to in other topics…
Otherwise I dont really see problem with MCT.
It just need to get to higher temp, and maintain them longer.
Maybe the reason is simply that those labs always use the same fast method, whatever the sample.
In case of most oil, one doesn’t directly see issues. While with MCT, if one does not evacuate it (needs to add at least 5 minutes at 320°C), it messes up with the next two analyses. The other oils will also promote some mess at some point, but it generally doesn’t impede analysis.
In my case I simply analyse any tincture the same way, with a longer method anyway.
The other oils somehow promote some mess too, You barely see none of the component in the chromatogram. At least with MCT, you see series of big sharp peaks, you know it is here.
Attention must also be paid with the strange engineered extracts people often send for analysis…
please dont use honey cut lol but “pee gee vee gee” might be a good starting point lol sorry i really wish i could say more but i need to keep my job right now
testing for titanium would be on an ICP, not a GC so shouldnt be hard to find a lab to test MCT oil. Yes too much organics can shut down the plasma flame but its not like GC or HPLC where it gums the shit out of everything
