THC. they were all tops. clearly THE best buds all three of them could find. at least 2 percentage points higher than I usually rated that strain of flower. blew me away with how well they had all selected their best work.
I’ve found the FID calibration to be solid for months or even years. and I get feedback from my 3rd party lab on a daily basis. I do have commercial standards, but suspect they’re shot at this point. unopened too. accounting wouldn’t purchase the vials to dilute the damn things.
my injections are (were when last calibrated) way better than any of my minions. but they can get within 10% of reality on a regular basis, so are no worse that the techs running your samples in a commercial lab.
I simply calibrated using a couple of my standard products using the results from my favorite lab. then challenged with different tested material. got it dialed in. would prefer to have commercial standards involved, but don’t really need them for many of the questions I ask.
I did have to recalibrate after the last kief injection**. I tried solvent washing and messed up the column by drying it too fast. they haven’t bought me a new one yet, so I’m trying to get the old one dialled back in. it gets me within 10% right now, but the peak shapes suck and I’m not happy with it at all. it still gives me useful information.
I can’t imagine flying blind…
which is why I have a calibrated bioassay team as a backup… Organoleptics: In House QC?
ran into a chemist working at analytical 360 about 5 years back who was working hard at calibrating himself on THC. Took it as a challenge. I’m probably out of spec at the moment
** it might not have been kief. It may have been a minion trying to figure out edibles injecting sugar or god knows what?!?
