Quick note:

I know I had decided I wasn't interested in providing support for this thread, but a trick that's worth considering: The easiest way to make 0.1N acid, is with acetic acid, which will work as well as mineral acids like HCl or H2SO4 when titrating nicotine.

How do you make 0.1N acetic acid?

Get some quality name brand white vinegar that's labeled as "diluted with water to 5% acidity". Vinegar acidity is expressed as wt/volume, so 5% acidity refers to 50 grams of acetic acid per liter of product. The normality of 5% vinegar is 0.8326. Vinegar acidity is tightly controlled during manufacture, especially among the better name brands because full potency is needed for it to do it's job when using it for pickling.

To make 1 liter of 0.1N acetic acid, dilute exactly 120 mL of 5% white vinegar to 1 liter with distilled water. To make 1 liter of 0.12N acetic acid, dilute exactly 144 mL of 5% white vinegar to 1 liter with distilled water.

If you screw it up, add oil and pour over salad.

I read and continue to read dvap's thread on nicotine content testing DVAP we owe a huge debt of gratitude for this information, vaporer & exogenisis thanks for supporting DVAP in ideas and brainstorming. Pornbjorg, thanks for starting this thread and putting where to get supplies for people. I already had purchased mine after reading DVAP's instructions. I have been buying liquid from several places and testing my liquid as it comes in also just to know who I want to buy from in the future. Again thanks so much for providing your time and knowledge and sharing this information. And we all owe DVAP alot for actually doing all these experiments and sharing his results at his own risk.
