Section 7: Application Note - Solvent Saturation
Below is a real graph of a full extraction run using the Extraction Finder in Wavelength View. The
Extraction Finder tracked Chlorophyll (blue) and Cannabinoid (orange) signals. Note: The Chlorophyll/
Cannabinoid ratio (grey) signal is for the purposes of this manual only.
Cryo-Ethanol Extraction Run - Recirculation - Extraction Finder Logged Run Data
A. Filling System - The extractor was being filled with ethanol
a. No flow over sensor; no signal
B. Agitation Then Soak - The extractor was agitated then went through a soak cycle
a. No flow over sensor; initial signal noise due to mechanical vibrations
C. Flow Started/Equilibrating Flow - The flow for recirculation began
a. Full flow over sensor; signal spikes then drops after initial fluid flow
D. Recirculating - Extractor recirculated ethanol over system
a. Full flow over sensor; signal increases/decreases as Cannabinoid concentration equilibrates
and becomes homogeneous in ethanol
b. End point determined by both Cannabinoid and Chlorophyll signals (and their ratio)
becoming stable/unchanging
E. Emptying System using N
a. Extractor being emptied with nitrogen gas and system no longer chilled; Signal of both
Cannabinoids and Chlorophyll decrease
F. Emptying Residual Alcohol from Extractor - Extractor reservoir emptied
a. Decrease in both Cannabinoid and Chlorophyll signals; increase in ratio of Chlorophyll to
Cannabinoid from system heating (ethanol preferentially extracting Chlorophyll in
reservoir)
