benzyme: I was thinking more along the lines of purity, and whether or not your getting some carcinogens in the tech-grade nps. For example, some canisters of butane have a warning on them about containing substances known to (the state of california) cause cancer. I'll do some more reading anyway.
Not worried about vapor exposure at all. More worried about cancer. I also understand that theses hypothetical 'carcinogens' would be insoluble in any solvent thats going to contain alkaloids, so no worries there. However, solubility, as I understand it, is not black and white. for example, PbCl_2_ is very slightly soluble in pure water, but is considered an 'insoluble' salt. I'd rather not have trace amounts of some unknown carcinogens in my extract. What do you think about this aspect? Wouldnt ACS-grade be safer in this aspect?
I dont know what you're talking about troubleshooting? Not having any technical trouble, I'm just trying to keep future me healthy.
Are there any food-grade nps that would work here? What type of food-grade volatile nps are you using?
Thanks Flickedbic. Exactly what I was looking for.
