Perhaps a little TC could help, maybe an Evolv pre-release?
Just kiddin' - put those sensors down!!!
Yeah, besides, I am not allowed to talk about that 22kW board yet anyway.....Perhaps a little TC could help, maybe an Evolv pre-release?

While looking at mikepetros' research I discovered that my all-day go-to kangertech would most likely go over the 450 degree of safety IF I chain-vaped with half airflow. So, taking that into account I no longer chain-vape and use a wide open airflow! I also lowered my wattage some.
Mikepetro even took time to answer a question I had.
I am very grateful to him and his amazing research to keep us safe.

We were asking for this back in 2012 when I joined ECF.
I forgot what the excuses were in 2012 - 2016
before the FDA thing came down.Oh wait.... I think it was buying racing boats with advertising on them n' stuff,
...that stuff gets expensive. How many years does it take of making millions ..... I'm sorry, but the vaping industry is about as disappointing on many levels as your garden-variety politician. Hopefully it doesn't take as long as it did for tobacco companies with cigs?
Glad to see members of the vaping community like Mikepetro attending to this to help fellow vapers though.
Bravo.

That's a slick, but expensive solution. Separating out the color spectrometer, you still need a collection means and settle on a test method which will depend on your collection technique. Probably the easiest is using a water based trap. Then it's a question of whether an inexpensive colorimeter will be sufficient or you have to step up to a quality UV-vis spectrophotometer instead (big bucks).
May be time to go back to materials and methods these guys are using to get an idea of what can reproduce the accuracy of the systems they chose. As I've never tested for aldehydes (that I can remember doing) I'm barely a toe step up helping to a viable, affordable solution (heavy on the affordable, not the Thermo/BD/Hach crowd).
oops, forgot one more thing. How will you generate the airflow so you can collect the effluent.
Yeah, after pricing that stuff out, I may just hang up that formaldehyde measuring idea. I would rather use the funds to replace my sidewalk. I dont make any money off of vaping so it would be hard to justify that kind of REAL money.
I am attacking it from another angle. I am striking up relationships with folks who do have access to the right equipment and funding. I am presenting my findings and theories, and trying to influence some of these guys to alter their test protocols to include variables that have been overlooked. So far, the work I have done has been received well by some of these PhD types. Maybe I will stand a chance of influencing some better tests.

That sounds like the way to go. However, it still doesn't resolve the puff thing. There has to be sometging that will pull air through for collection and has to give a consistent vapor flow rate. I think the nightmare of getting that right was a reason Wang went the way they did. Otherwise you're back to a thousand configurations all at varying temperatures.
If anyone can put the funds behind something like this and contract with the proper investigators I would put Evolv on that list. They brought it up to begin with, and they want quality temp control to be relevant. I don't know their business model or capital available, but if they are seriously going down the PMTA path, they might as well get these data out of the way early.
I asked Dr F to look at my blog and asked for his opinion:
Aldehydes are DEFINITELY related to temperature, NOT to power or anything else.

That sounds like you are saying the exact same thing Dr F said above about "aerosol yield", just in a different way
Ah, just to maintain perspective, it is related to temperature and power is one of the variables that contributes to temperature. So power is of some importance at managing temperature.
I see the point of the thermocouple sampling a specific location and might not be representative the while package, but. I think the tight correlation when in TC mode with reported temps makes me less concerned with missing the whole picture.
Power is a variable that contributes to temperature, as do several other variables. However TEMPERATURE is the trigger that throws VG into degradation.
I totally agree, which I why I always chose 1 coil off center. Anyway, the whole context here was showing folks who dont have TC what their coils are running. Lets face it, if you have TC then you dont need the thermocouple at all.
TBH, until your data, I did not have faith that the temps reported in TC were necessarily correct. That was my main beef about assuming TC matters in real world temp settings.
I also agree airflow is a big issue in predicting real world behavior. In some ways I'm sorta happy I now prefer a looser draw, so more air over the coil and wicking. Even when I go back to my mtl tanks I leave the air wide open, but that's just me.
