there is a TLC kit linked in in house analytics.
haven’t tried it.
I have used the Cannatest setup for state mandated testing in OR. accuracy is operator dependant, and without a densitometer is also rather subjective.
testing isolate should be less problematic than testing flowers. but if you’re distilling, and manage to degrade/isomerize your product, figuring that out via TLC will take some work.
Cannatest’s website is still up, but they don’t seem to be responding to emails. I assume they’ve moved on.
