TC - the maths and the real world

[scrumpox]

I can see what you mean when you say the numbers don't matter if you're enjoying the vape but then again the more accurate the devices get the better. You're right that it's the vape that counts but if all devices gave an accurate temperature across the board it would make it easier swapping atties around and even sharing your preferences with others for a given atty or juice. I think we'll get there on the end with advancements in the boards and probably just as important the wires we use.

Yes, don't get me wrong on this, I'm not anti-accuracy, just anti-complexity. Like you, I believe they will get there.

If SS is unsafe then we're in real trouble ... ... I'll have to start using black atties again ...

There's talk of 304 SS being safer than 316 but as with all things vaping wire, there doesn't seem to be a great deal of concrete info to base our decisions on (as far as I can determine). Obviously heating a thin filament of SS to over 500F and inhaling the air surrounding it presents a different situation to that of a SS atty, but to what extent we should concern ourselves with it, I don't know. But I sure would like to for the various wires we have at our disposal now. I'm sure a metallurgist and chemist could very quickly run tests capable of providing those answers, I just wish they would.

Yeah, me too. Trace metal analysis has been done for kanthal and it's not a cause for concern. I think it's unlikely we will see such a test before these different wires become popular in stock coils. I find it very unlikely that any wire is going to be a cause for concern at normal vaping temperatures, and thanks to TC we are protected from overheating. But this is only really a gut feeling, my knowledge of metal/materials chemistry is poor.

An atomizer and a little gas chromatography would give useful data I would have thought. That and expert assessment of any risk likely from the type and level of elements found.

Wouldn't have to be a topflight scientific study to placate me. You're some kind of scientist aren't you, Dan? Sort that out for us with your science friends eh?

Ha, yes, I am a research chemist but my field (organic synthesis and medicinal chemistry) is quite far removed from this, which is analytical chemistry.

Granted, it would not be hard to do, but you need an automatic smoking machine and a pretty specialised analytical machine called an ICP-MS. I don't know anyone personally who has either. The most likely way to get the study done is pestering people like Konstantinos Farsalinos, who already have the kit and a validated protocol ready to go (or knows people who do). Researchers also need funding, I would certainly contribute to a small crowdsource-funded study of metals in the emissions of different wire types. Maybe that's a viable approach.
