Thanks for all the replies so far on this topic, I think it's an important one to consider for anyone vaping, especially if you are DIYing your own liquids. I did see the thread that
randyith had mentioned which stated that one of their competitors sold a nicotine liquid that tested far above what it was labeled to be.
This is one of the sources that prompted me to buy a testing kit for myself, and of course do some research and ask some questions. Consistency is important to me when it comes to vaping, with everything from the PV itself, cartomizers, batteries, but particularly with E-liquid. This is the aspect of vaping that if it's done wrong it can actually hurt you.
I'll make a purchase at RTS hopefully within the next few days before the sale ends. Im just crossing my fingers that the items I want will stay in stock with this big sale going on.
I don't know if this is an appropriate forum but I could test the 100mg RTS PG base liquid I plan to get and post the results here if there is any interest.
Of course Id post my method of testing as well, and Id point out that small differences in results do not point to a bad liquid. I actually expect anywhere from a 1 to 10 percent margin of error based on the small sample sizes I'll be testing, and the fact that I don't have professional equipment.
However this method will give a ball park figure and send up a red flag if the liquid is way off in terms of NIC content. If for example the 100mg liquid tested lower than 80mg or higher than 120, that's when Id be concerned.
Ive read up on most of the steps I need to take to make the test more accurate, shaking the bottle containing the nicotine, and extracting from the center seems to be one of the most important things you can do. having the nicotine evenly distributed seems like it will improve test results. I'll follow all other steps thoroughly and run a pretest on another liquid so that I have a better understanding of the process.
As a side note I can say this about RTS, I haven't tried their liquids yet but they have great deals on Nicotine, Ive been to over a half dozen sites and price wise this site is more than competitive. I've actually seen 100mg bottles of nicotine being sold at about twice the price of RTS.
