Cleanliness liquids - research team prof. Etter 0

Courtesy of Mr. prof. Jean-Francois Etter I was before my eyes the text of the most recent publication of his team, this time on the purity of commercially available liquids. Analysis was performed by gas chromatography and liquid chromatography, and was tested nicotine content as well as the typical contaminants that are normally present in such fluids. The results really optimistic. In none of the samples, there was no presence of ethylene glycol and diethylene (probably remember the famous FDA reports before almost four years, at which every move opponents cite e-cig). These tests were performed according to the procedure used to examine the contents of glycols in propylene glycol used in pharmaceutical production.

I will not bore you details of analytical - they have at this point irrelevant to non-chemists. It is important that all tests were performed in a manner most similar to the analysis performed for use in nicotine replacement therapy. Brands liquids selected after analysis of popularity among users in the United States, Britain, France and Switzerland. They were EirHorse, Ecigexpress, Janty, Totally Wicked, Vapor4life, sedans, Johnson Creek, Tecc, Intellicig and Dekang. All liquidy easily passed on nicotine content, which generally did not differ from the data on the label by more than 7%. In conclusion, Professor. Etter says: the quality of some brands is surprisingly high, although in some cases the production process or supervision over the quality seems to be below the standards required for medical products. The highest content of typical contaminants found in the case of liquids ecig Express (USA Mix), Jana (Orange), Vapor4life (555, Nobacco Juice).

Exceed the value of pharmaceutical products, but, as the Etter, continues to be negligible in comparison to conventional tobacco products. Looking to turn on the light side - the purest is tasteless base of Ecigexpress, wherein the total content of impurities of nicotine is approx. 0.2% (relative to the nicotine contained in the fluid). It's a really good result. At the end of the prof. Etter says that these tests are only fragmentary, indicating the direction in which it is worth to follow. To further learn what we breathe, examine fluids (and created a cloud of them) the presence of substances such as vegetable oils, acetyna and dwuacetyna, food colorings, flavorings and others. I wonder when Irish researchers announce the results of similar studies liquids the most popular brands available in our market.

Currently, the only e liquid studied by Irish chemists is eirhorse. Test method is known, pharmacopoeial procedures are available, and the gas and liquid chromatography are also normally used in laboratories. I think e-smokers would be really interested in such results
