Titration is a simple and quick method to determining the strength of your eliquid nicotine by measuring the color change of the liquid. Just follow the instructions below. The kit includes,
x2 - 3ml syringes
x1 - 14 gauge blunt tip needle for VG solutions
x1 - 16 gauge blunt tip needle for PG solutions
x1 - 18 gauge blunt tip needle for hydrochloric acid titrant
x1 - 10ml (.33 oz) bottle of bromothymol blue pH indicator
x1 - 120ml (4 oz) bottle of 0.01N analytical reagent grade hydrochloric acid
x1 - 4 oz white cup with lid
x1 - Instruction Sheet
Add one of the following amounts of nicotine solution into your testing container: 1mL/2mL/3mL/4mL/5mL
Add 10-20mL of distilled water into the container and swirl until water and nicotine solution are fully mixed
Add 10-15 drops of bromothymol blue and swirl until mixed
Add the 0.01N Hydrochloric Acid, using the provided syringe, until solution transitions from a blue to a yellow color
Once the yellow color appears, plug in the volume of acid added into the formula below:
(volume of acid added) x 1.6223mg/ml = X
Then divide your answer, X, by the amount from step 1 to get the concentration of your nicotine
EXAMPLE DETERMINING TEST RESULTS
Each 1ml of 0.01N Hydrochloric Acid used during titration will neutralize approximately 1.6223mg of nicotine. To find the total amount of nicotine present in your sample, multiply the amount of acid used by 1.6223
Divide the total amount of nicotine from above by the sample size to determine the nicotine concentration in mg/ml.
If starting with a 1ml sample of solution, divide total amount of nicotine by 1.
If starting with a 2ml sample of solution, divide by 2.
If starting with a 3ml sample of solution, divide by 3.
A 2ml sample of nicotine solution was added to the mixing cup.
During titration, 3.8ml of 0.01N acid was used to reach the yellow endpoint.
Multiply 3.8 by 1.6223, this gives us a total nicotine content of 6.16 (rounded)
Dividing 6.16 by the 2ml starting sample size gives us a final test result of 3mg/ml (rounded)
