Still getting harsh throat hit, im running out of ideas.

Some info on testing here https://www.nikitest.com/e-liquid-nicotine-test-lab/e-liquid_test_kit_works/

Basically you use acid to neutralize the nicotine, the amount of acid use is proportional to the amount of nic in the sample being tested.

Say I have 0.1N acid ( which can be made by adding 12ml of 5% vinegar in 100ml of distilled water). I put 1 ml of " supposed" 18mg /ml juice in a test vial. I then added 2 ml of distilled water to the vial and 4-5 drops of pH test liquid (6 - 7.2, can be found at most pet store that carry fish). The solution will be blue. Slowly add the acid; it will turn green then yellow. When it turns yellow, stop. Multiply the amount of acid used by 16.22. That is the amount of nic in the vial. The more nicotine you test the more accurate the result.

This test method was developed by DVAP, all credits goes to him. Search this forum for more information.

Note that 16.22 is used above is because my acid is 0.1N and not 0.12N.

Great, thanks a lot for posting this!

Are you doing this with an already mixed juice or just the raw nicotine solution? You should be doing this with the nicotine solution as it comes right from venders shipped bottle. Any other way and your test is flawed as added flavorings or any other outside influences such as water, VG, PG will skew the actual results.

You can test mix solution and the results should be ok as long as acid was not added to the mix. Otherwise it will give you a low reading. I normally test unflavored ; water, PG and VG are all neutral (PH 7). Flavors can have some acid.

If the juice is dark or has coloring then it will likely be impossible to detect the transition from green to yellow.

My wife and her cousin cant vape my ejuices.I thought it was the pg in my juice but then I made another batch with no pg just vg and it still hurts them. Maybe it is the nic and it just effects people differently.

I had same trouble. You have made your throat sore. Enhale mouth and exhale nose and mouth only. No throat inhale. 2- 4 days of control mouth throat inhale only should heal the throat. When throat heals, alternate technique with minor throat inhaling to keep enjoyment level high.

Actually, that should read "may skew the actual results."
