40mL, Amber Glass, Class 100, EPA VOA Vial Assembled Kit, 100/pk (National Scientific # B7951) Recommended for discrete water sampling under EPA 40 CFR 136 Guidelines for Establishing Test Procedures for the Analysis of Pollutants and EPA 40 CFR 141 National Interim Primary DrinkingWater
Approximately 0.2g ground samples (except in the case of acetonitrile where we ran out of marijuana and only used just over 0.1g) were extracted with 40mL solvent in a precleaned VOA vial. As seen in the bar graph, methanol was the most efficient extraction solvent for delta-9-THCA (analyzed as THC).
