** less reliable than later results due to later improved vapour-collector design change.

So not really much 'nicotine' as %age is lost to combustion or deposition on coil,
no significant trends seen.

Except it looks like a good idea to keep atty coil 'wet & gurgling'
to keep it from starting to glow during a draw, even then > 90% came across.

Other observations:

Definately a small amount of acetic / lactic (or possibly formic) acid produced by vaping PG,
not enough to worry about by some margin.

The collected condensed vapour was sometimes clear & sometimes slightly cloudy,
not sure what the cause was.

The 'nicotine found column' relates to the of 'the main nitrogen' in nicotine (or possibly
nicotine-like compounds).

Can't really tell without sophisticated lab gear whether it
really is all actually nicotine, or substantially altered in any way (e.g. nic. oxide etc).

Updated per OP's Request---Thanks Exo!!

Thanks Sun

Hopefully having the results alltogether in the summary post (3rd in thread)
makes things clearer for first time reader.

Unless there's some unusual parameters anyone can think of,
I can't see any further ordinary tests being done, except maybe the exhale ones.

Nice presentation exo.
A lot of work there and it tells a definitive story.

Let the myths now end.

Yes,
can't see anyone saying there's little nicotine in vapour anymore,
I hope.

What's to be confused about TV ?

**DVap** · 01-14-2010, 03:24 AM

TV... read the far right column that says "% recovery".

If you're still confused, pop a snus, and all will be well.

**exogenesis** · 01-17-2010, 09:23 PM

Is that scroll bar causing a problem by 'hiding' the %ages?

If so I'll cut-down the table width at some point.

Pop a snus anyway TV - oh you already have
