Application Note: Does Syringe Filtration Impact Recovery of Cannabinoids Prior to Potency Testing?

Cannabis extracts from cannabis flowers or in cannabis-infused products, tent to heavy particulates. Therefore, an essential element of sample preparation prior to analysis with HPLC is the removal or particles.


We tested four different 0.2 µm Sartorius Minisart filters, differentiated by their membrane material (regenerated cellulose, PTFE, Nylon with a quartt pre-filter) to test for the presence of leachables and retention of cannabinoid analytes.
