Frequently Asked Engineering Questions

What is the difference between gross rosin yield (%) and true cannabinoid recovery efficiency (%)?

Gross yield divides concentrate output weight by starting flower weight (e.g., 220 g rosin from 1,000 g flower = 22.0% gross yield). True cannabinoid recovery efficiency divides total THC milligrams captured in the rosin (220 g x 76.5% THC = 168.3 g THC) by total THC milligrams present in the starting flower (1,000 g x 22.0% THC = 220.0 g THC), revealing that 76.5% of the plant's cannabinoids were recovered while 23.5% (51.7 g THC) remained in the spent pucks.

How much concentrate sample is required to verify live rosin potency and terpene retention at CannaApp?

Panel CA-LAB-03 (Master Chemotype HPLC + 21-Terpene GC-MS Duo, EUR 99) requires only 0.25 grams of live rosin, bubble hash, or dry sift.
