thanks for the help. we did test the material before we run it and got a clean result then re tested it after we processed it and was positive of pesticides. never happen before. thing the lab might have messed up.
yes. they asked a question. i will give them an answer. without opinion.
good point/ interesting idea. we cls the material then gave it to a 3rd party to have it refined looks like the clear amber stuff skunkfamers posted yesterday on Instagram. I wonder if that increased the amount. lost about 20 to 30 percent yield having it refined. most lost is winterizing it. but must be some loss in removing everything you don't want. did u or joe make the amber stuff on Instagram looks nice, we just figure out how to turn that stuff into shatter.One of the reasons we got a GC, was to protect ourselves and our equipment from pesticides on incoming material that isn't from our garden. If it is contaminated, it fouls not only the concentrate, but the recovered butane and internals of our systems, requiring a full dump and internal cleaning. It only took once for us to lose our sense of humor.
Your lab ostensibly screwed up, but you may have also concentrated it some with your extraction, sooo the truth may be in the middle. A recent Oregonian expose', revealed the presence of both pesticides and residual solvent in a high percent of the random concentrate samples they had tested, so it is a problem we're all stuck with, unless we only process our own material.
At what concentration levels are they showing up in the concentrate?
thanks. yea is been lots of fun cleaning all the equipment.Joe or James must have been the rascal who posted a peeeecture, but we will typically lose 15 to 20% winterizing and another 20/25% at the Kugelrohr, when running clear. THC yield versus potential is typically around 80%.
Typically the clear from a Kugelrohr is not a shatter, but Joe has made shatter using very tight fraction control. You can discuss it with him at joeoakes@skunkpharmresearch.com
The monoterpene fraction smells/tastes like ass, so we haven't added it back.the clear you guys are making are you keeping the nature terps or adding fake later. my 3rd party friends doing a process that keeps all the nature terps. like it way better that steam diss clear with fake terps. my new goal in life is to figure out that process. makes the cleans safest best tasting medi I have ever seen.

how would you test more than just a sample. if I test the whole thing there would be no wax for me.ya but u tested a sample. not the entire batch lol. just scrap it . or tell people exactly whats in it let them choose. its better then theblack market. when u have noooooooooooooo clue.

Okay... Everyone saying (Throw it away only use clean material) you're a bunch of impractical idiots, and I'm not just saying this without a reason let me explain. If you live in CA then you know that we grow grapes.... a lot of grapes. Myclobutanil is predominately used in CA, I mean like 90% or so of the Myclobutanil is used here in CA, pretty much the only other place it is used is France. Its used to control PM on grapes and is sprayed by atomizers or dumped from aircraft over vines to get onto the plant. It travels literally 100's of miles in the air and if you grow out doors pretty much anywhere in CA then you have it. You have it in low or high doses which is why it comes up so often. People know not to use Eagle 20 but it still comes up in an outdoor field.
Graywolf, Ive followed you for years I mean nearly a decade man and this is hands down the weakest chain of responses I've ever seen from you, as a matter of fact it was so poor that I made an account so I could post this. You almost always have an answer to every problem or at the very least can point someone in the right direction. I have the upmost respect for you by the way.
Pesticide removal is the right way to go. Medicine can still be safe if the pesticides are low reduced below detection which in most cases is between .1-.2ppm. You take in 10x more pesticide eating an apple. Hexane washing is on the right path, most of these pesticides are virtually insoluble in saturated Aliphatic hydrocarbon, but you still have to filter it out so you need to use size exclusion to remove them. a 15 micron filter will probably get you below detection.
The other option is saponification, most of these pesticides undergo hydrolysis under highly alkaline PH. Let it sit for 8-10 hours at a high ph preferably 10-12 and then mix thoroughly, make sure to rebalance or when you begin to take off your solvent you'll make soap. hope this helps people out.
Thanks for the clarification on the 15 micron filters and suggestion of Florosil! We've use silicon beads for column chromatography with Hexane and Acetone to separate fractions, but haven't gone after insecticides.So I did not get a chance to read this till now.
I should clarify, you want a 15 micron filter but it needs to be reverse flow aka at the top of your column so that material cannot travel with gravity through the column itself. that being said the filter alone is not enough, you need chromatography grade silica. Ichromatography is the place to go and I recommend florasil 75. for removal of 60% or so of the pesticides you'll find in cannabis oil.
there is another way that works very well as I said before, saponefiaiton or esterification of the ester group on the organophosphates you'll run into. You need to cleave off that ester group attached to all organophosphates. This can be very risky as most of these pesticides when cleaved can become highly highly toxic like where the LD is no more then a 1/20th of a ml. The advantage to this is when you do this process you greatly change the polarity of the molecule allowing you to adsorb it onto chromatography resins. May I recommend reverse phase with hexane. start here let me know how it goes theres a lot to it get to work.
