Any interest in determining nicotine--by DVAP

Plausible...I'd say very much so. Being hidden means a slower adsorption rate.

Honestly, I don't know. I suspect the vapor particle size larger and from other articles I've read seems to confirm it.
My question is , Is there a better pH range to titrate the nic solution for a better adsorption rate?
I don't have access to equipment that can measure the vapors pH. If it were skewed to far to one side, the readily available amount would be increased or decreased.
Alot depends on how much is deposited in the lungs, dissolved in the particle, that will slowly adsorb via the lung tissue. It seem much more is available to the mucous membranes.
To me this all supports the fact that most people claim to vape longer time frames than they did when they smoked. It is knownthat nicotine has been adjusted in smoke to enter the system very quickly.
That would be a nice advantage to apply to vapor if possible and not be detrimental.

The pH of e-liquid seems plenty high enough to absorb whether it be mucous or pulmonary.

We may very well be looking at particle size? Cigarette smoke has a very small particle size, while I would suspect that vapor particle size is much larger. If we view vapor as a solvent/solute system, where nicotine is the solute (the stuff dissolved) and PG is the solvent (the stuff doing the dissolving), then a "particle" of PG would present to the lungs as a container, the contents of which (nicotine) aren't readily obtainable. The bigger the container (particle), the more content (nicotine) is hidden from the view of the lungs.

Plausible?

I have proposed this before, and there is some anecdotal evidence to support it - that the nic is not so much missing but more slowly absorbed. By I don't think this is the (main) answer re missing nic. But is the answer re lack of buzz/hit.

"Totally Wickeds Platinum Ice and Totally Wickeds Decadent Vapour Premier range are the first true U.K Produced Electronic Cigarette or E-NI liquid nicotine products. We have full batch documentation for both the Freebase Nicotine and the Propolyene Glycol used in the fluids, these documents can be viewed on the listings page."

Has Totally Wicked figured out away to Freebase it or am I misreading their new advertisement?

Freebase nicotine is simply unprotonated nicotine. Got e-liquid? You've got freebase nicotine.

I think they're saying they've tighten up their supply chain for these product lines and from pure nicotine to e-liquid, it all happens in the U.K. I consider this a good thing, for a number of reasons.

Yes, the new TW liquid is probably a little bit better because it is based on a higher purity nic to begin with. So, there's agreement here that juice is by and large all freebase; and the newer, purer juices will be even better in this regard. Marginal perhaps in this respect, but a lot lower in cocomitants (TSNAs etc)

ps: nice to see you dedmon

As far as TSNA's (Tobacco specific nitrosamines), you're probably quite aware that these are an issue with tobacco derived nicotine, but not with nicotine arrived at via a synthetic route. Still, I'd hazard that as far as TSNA's are concerned, one puff off a Marlboro is good for as many TSNA's as you'd get from lord only knows how much vaping.

Kinabaloo,

That is exactly what I'd like to see is a faster adsorption for the buzz/hit.
Less time vaping more actually like smoking, the last one thing you don't get.
That's reason I looked at the pH results so hard.
Also,so many come in fruity flavors. Seems this would drive them acidic.
I've even seen citric acid listed in some ingredients

I know this figure : 7000 !

I think a fair portion of vapers are hoping for this, just as you describe.

The citric acid is odd; it's a nice taste but won't make it into the vapor. Shouldn't affect the freebase content.

There's not a whole lot more buzz with the new juices (possibly with PEG) so this still needs some more investigation; at least we have some ideas.

Yea.. the citric acid scares me for reasons I've previously posted.

Fruity flavors tend to come from esters, which are derived from alcohols and carboxylic acids via dehydration (pull H off of the OH group of the alcohol, pull OH off of the COOH group of the acid.. often facilitated in lab experiments using sulfuric acid as the dehydrating agent with a little heat added).

Esters, as far as I can recall, tend toward pH neutral, and are relatively volatile, so it's easy to get the smell/taste from them.
