To the best of my knowledge, minor alkaloid content will only equal a certain percentage of actual nicotine content.
Let me explain this as I understand it.
For example: if you have WTA juice at 24mg nicotine and, assuming the minor alkaloid content is 2.5-5%- let's suppose you dilute the juice by 1:1 with
just nicotine/pg/vg; what you end up with is the same nicotine content, and half of the alkaloids the base liquid contained.
WTA as a whole can be indicated in proportions one of two ways-
1.separate from the base concentration of nicotine.
Example: let's say you know exactly how much WTA you want per bottle and use a fixed ratio, you put the known amount of WTA concentrate in, then add your liquids and titrate nicotine upwards to adjust the total nicotine content to where you want it. You can use simple math for this, since your WTA base will only contain so much nicotine at a given amount. Simply put, you add WTA and then nicotine to get the strength desired.
2.the WTA will be directly proportionate to nicotine content (nicotine being the indicator for strength of the alkaloids instead of a separate value)- where WTA (which would include nicotine in the spectrum of alkaloids) is concentrated to a point that the nicotine is indicative of total minor alkaloid content. In this instance, higher nicotine would equal higher amounts of minor alkaloids, and the entire process would be much simpler but require larger amounts of WTA to equal the same concentration of nicotine.
Example: Your WTA is where you derive your total nicotine in a given liquid, so when the nicotine is just right, so is the WTA. Only addition of full-spectrum WTA is used in order to adjust the strength of the liquid, no titration of nicotine is needed.
In either case, additional nicotine could be added, but depending on how the concentrate was formed and how concentrated the minor alkaloids were, the amount to dilute by would vary greatly to achieve the desired results. This is why making WTA juice isn't a walk in the park.
