Simple, easy DIY test for mg/mL nicotine. A Follow Up on DVAP's Method

[Frost]

Nice test !! Being a chemistry geek, I actually enjoy doing stuff like this, and that it can be done with readily available materials is fantastic. Thanks for posting.

Chemistry geek aka an actual chemist in the forum? That would actually kinda put me at ease that an actual chemist approves the math here lol ... although I really have no way of confirming your qualifications lol

An actual chemist approves the math.

My qualifications are on the thread where I documented the source method(s) for this determination along with quite a bit of validation work, see the references in Þornbjörg's original post if you need more information.

Where does this number come from? 19.4712
I know its probably right in front of me to see but it would be nice if this is explained in the directions.

Thanks

Well........you might look in the original thread where all this was worked out by a REAL chemist to start. http://www.e-cigarette-forum.com/for...-nicotine.html

Then, I'd be looking at post #'s 365, 374, 377, 386 & 408 just for some of the highlights.

You decide.........produce a kit to sell and its Knowledge Infringment as well.

Shameful.

If that isn't enough...............
Look here: A question for chemists about eLiquid production

Or an excerpt from here: My First Post: About little about me.

"To win a bet while I worked for a video game company, I smoked a cig while I had two 17mg snus packs in my mouth, and two nicotine patches on, immediately after chewing high strength nicotine gum for 10 minutes... without getting light headed, dizzy, or having heart palpitations. The bet was won by my not vomiting. Yes, there was medical personnel present, armed and waiting for my collapse."

Interesting reading I think.

The only problem I see with this method is that many e-liquids contain acid(s). As such, the test will not provide extremely accurate results. For example, all four recipes at the wikipedia article list a concentration of acid from 1 - 2.5%.

I think the additives 'problem' is best answered in this thread post
(just posted a reply there for that question popsec)

I told you it was right in front of me. rofl. And yes I did read that thread.

So people can understand where my magic number comes from...

This post...
Any interest in determining nicotine--by DVAP
... shows where I ask DVap -who not only has a degree in Chemistry, but also works in a lab- for a little help with math (I'm so very very rusty... sigh... what you don't use, you do start to lose... don't ask me to calculate quadratics, lol).

This post...

...shows my math, if you'd like to verify it yourself.

My qualifications don't include college, but involve hands-on lab work side-by-side with a high caliber chemist for a few years. Sadly, haven't worked in anything resembling a lab environment for about 10 years, unless you count cooking or mixing drinks.

I'm in! THANKS very much...I have a whole Big bottle of VG nic that is either mis-labeled or faulty, will soon find out which.
