Update: sorry for slacking on the math and stuff, I have alot of tests and stuff going on,
bloodwork and xrays (my dumbass broke BOTH my arms (left wrist, right arm) in seizures that night -_- )
We miscalculated the speed at which Everclear Evaporates <-- main culprit
How much did you originally dilute down into the mixture for dosing?
I think this is a very strong reason that when experimenting with chemicals with a dosage ranges under 5mg, to never dilute down into one container more than is safe to accidentally consume and strongly consider (if solvent is safe enough) using larger than 0.02 milliliter per dose, like in safe for consumption alcohol solvents.
Sure may taste nasty having to take a half milliliter drop of alcohol for a dose, but that reduces the variance due to evaporation.
If a substance has a per dose of 100 μg, and a toxic level of 2mg, then weigh out using a milligram scale 10mg, dilute it down to 100 μg per X milliliters, and then immediately separate the mixture into separate containers containing no more than 1mg (10 doses) per container.
This would prevent the possibility of a toxic dose even if you accidently consume the contents of the entire container, regardless of evaporation.
So, the formulas are along the lines of:
(Disclaimer: I am not a mathematician, I'm a software developer, if this looks like an amateur did it, it's because I am, just putting out my ideas and it was fun as hell to figure out all this, and how to write it in a way that at least appears professional to the untrained eye. Corrections, suggestions or criticisms of the following are welcome and desired... but please don't insult.)
Dr = amount of solvent containing enough of the diluted chemical to consist of one dropped dose, at a low enough quanitity to prevent solvent toxicity and high enough to prevent dose variance due to evaporation.
Do = size of one dose in mg.
T = Toxic level of chemical in mg.
TDo = Amount of doses when if consumed reaches toxic level specified by T
C = Containers to separate out the resulting mixture for safe storage
Q = Quantity of chemical to dilute
So = Amount of solvent required
CSo = Amount of solvent per container
Number of doses with a toxic dose in it:
TDo = (T / Do)
Largest safe dose (number per container):
.........{ |_ TDo / 2 _|, if T / 2 > Do
SDo = { 1
Number of doses created:
N = (Q / Do)
Number of containers to employ:
C = N / SDo
Amount of solvent to use:
S = Dr * N
Amount of solvent per container:
CSo = Dr * SDo
Using above formulas with the above example:
We have 10mg of substance Z, dose is .1mg and toxic dose is 2mg, we intend to use .1 milliliters of solvent per dose.
Do = .1mg
Q = 10mg
T = 2mg
Dr = .1 milliliter
Number of doses for toxic levels:
TDo = 2mg / .1mg
TDo = 20
Maximum number of doses per container:
2mg / 2 > .1mg so we will use floor(TDo / 2)
SDo = 20 / 2
SDo = 10
Number of doses created:
N = 10mg / .1mg
N = 100
Number of containers to employ:
C = 100 / 10
C = 10
Amount of solvent to use:
S = .1ml * 100
S = 10ml
Amount of solvent per container
CSo = .1ml * 10
CSo = 1ml
