Can someone please tell me if there are good analytical quantitative results for compositon of VG and PG vapor from an E-Cigarette. I have viewed the concentrations posted by "thebestecig" people for their e -liquid (PG vehicle) but little else.

If I am going to try this e-cig I will make sure that I am as well informed as possible. Up until today I see very little quantitative analysis on products produced after atomization. I have read a fair bit on work done in New Zealand which definitely contradicts FDA results (political lobbying at its best).

Contamination should be a major concern for all that inhale this stuff and I hope that the "devil you know is worse than the devil you don't"!

Since I am a nicotine addict (having smoked for 35+ yrs) I know after having seen my mother die due to respiratory complications as a result of her having smoked most of her life, that I need a solution. I have tried gum and pharma nic inhalers, however these have not been successful.

The e-cig looks like a real contender. If the manufacturers are not willing to disclose what their e-liquids become after atomization ( reputable lab and biochemical analysis) and cannot quarantee no contamination with products (by products, etc) like PO then it will be awhile before I take the plunge. Perhaps regulation is the only way to wake up these manufacturers of e-liquids.

I need an alternative to regular cigarettes that will not damage further what I have damaged already!

Hi Klatu.

Ruyan did pay for additonal studies by an independent lab:\


As was reported in this article, was the fact that Ruyan had done further studies conducted by Pony Testing.

Pony Testing identifies themselves as:
PONY TEST(Short for PONY TESTing International Group),the leading testing organization, has qualification of the CNAS and CMA, gets mutually recognized agreement including USA, UK, Germany etc. 58 countries and regions. As a large comprehensive testing organization which runs on the basis of ISO/IEC 17925, the report provided by PONY TEST obtain international approval and international notarization & credit. Up to now, we have set up 4 large laboratories in China, 6 branches and 21 offices in UK, HK etc., formed an international testing network. In 2007, it honored "Deloitte Technology Fast 50 China" and "Deloitte Technology Fast 500 Asia Pacific". See http://www.ponytest.com/about-en.html


Here are the four new reported test results performed for Ryan by Pony and they are very encouraging. Note. Click on the photo after opening to enlarge the photo. I do not see any tar here and this is the most comprensive studies so far. Pony does not play games with their findings–--Sun

Klatu,

Welcome to the ECF.

If you've read the New Zealand study, then you have the best information that is currently available. Sun has provided a few more sources to check, but you'll just have to make your judgement on that data. There isn't any more that we could add that would give you any more assurance than what you could determine through your own investigations. We don't have 'inside info' :)
