That we don't get *100%* always just seemed like common sense to me, scientifically. I mean, it is mixing with air, your mouth, lips are not a closed system, etc.
However, in the case of diacetyl, I don't even want 80% or 90% of whatever amount may be "in there." 0% would be a good number for me.![]()
Yeah... Just like the Body doesn't Absorb 100% of the Oxygen in the Air, or the Nicotine / Flavoring in a hit, it stands to Reason that not all the Da/AP isn't going to be Absorbed.
None of this Seems like Rocket Science to me.
Test an e-liquid that you know has got Da/AP in it to get a ppm number.
Hook up an atty to a Fish Pump and pump out a 4 Second Hit into a Container. Let the vapor condense into liquid. Test for Da/AP ppm.
Hook up an atty to a Fish Pump and pump out a 4 Second Hit into a Vaper. Have Him/Her exhale into a Container. Let the vapor condense into liquid. Test for Da/AP ppm.
Compare:
ppm in e-liquid
ppm coming off off the atty
ppm coming out of the Vaper atty
Repeat with other e-Liquids / Vapers to make Mathematical Model.
Seems like something that could be done on just about any College Campus as a Semester Project.
