Vapor differs in composition from e-liquid

I found this in Jessica99's daily ecf post:

Vapor differs in composition from e-liquid

They're using "a novel analytical approach based on Secondary ElectroSpray Ionization (SESI)".

By gradually changing the settings of the “SESI smoking device” in order to simulate changes in the power of an e-cigarette (5 to 35 W), the authors confirmed an increase up to two orders of magnitude of some compounds in the gaseous phase compared to the e-liquid.

It has a link to this, which I'm not sure has not already been discussed in one of the forums:

US study on e-cigarette emissions quality

They however do not infer any toxicity from their results. No information is provided with regard to the type of e-cigarette used in the protocol.

The authors noticed that that volatiles were not emitted with a consistent delivery rate and link the decrease to either the depletion of the battery or the depletion of the cartridge

That novel approach might actually help : EU isn't quite as overboard as the FDA, but they will ask some emissions profile too. With a real time analysis like that, the costs for providing that data could be in a reasonable range where medium and maybe even small operators could stay in the business of making and marketing liquids.

Unlike the gazillions of buckazoids the FDA figures for their application. That kinda dough would squeeze everbody out. Except the big BT players. Which is the way BT wants it. Which is the way they 'bought' it from the FDA ...

they're hitting a "cartridge" with 35W?!

Yeah.... I wondered about the second link there which points to an earlier study (nov '15)

"in the framework of a comparative study of their products with concurrent ones. Size spectra were obtained from another analysis but on the same sample."

The comparative study was on the Phillip Morris 'heatstick' - cartridge based I believe and not really an ecig as we know it.

Imperial Tobacco runs a study on Philip Morris’ iQOS (heat stick)

Very Interesting. Thank you for Posting this nicnik.
