The ppm of residual solvent in an oil sample isn't equal to the ppm of residual solvent in the oil sample vaporized and diluted with air.
The residual standards are BS, at the actual concentration level the residuals are non-toxic, and undetectable to the unaided senses.
Could you elaborate?
Definition of elaborate
1 : planned or carried out with great care - took elaborate precautions
2 : marked by complexity, fullness of detail, or ornateness elaborate prose
I'm done elaborating.
GW, the table of odor thresholds you linked to states 1,200 ppm for butane. For your senses to experience 1,200 ppm of butane the BHO would need to have a butane residual of 15,900 ppm, assuming the 13.25x dilution factor from my presentation.
Also the 1,200 ppm odor threshold referenced is against a neutral background of pure nitrogen, not a vaporized terpene rich dab diluted with ambient air.

Could you respond?
