Does syringe filtration impact recovery of cannabinoids prior to potency testing
30 Oct 2020The objective of this study was to determine if using syringe filters (Sartorius Minisart® RC, SRP, NY and NY Plus, all 0.2µm) either released interfering compounds or retained cannabinoids during sample preparation for HPLC testing. A blank matrix specimen of homogenized nettle leaf (Urtica dioica) was used for calibration and control and analyzed without cannabinoid for leachables. In addition, a true cannabis specimen was filtered using each of the four different filter types and analyzed for recovery of cannabinoids by HPLC.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.FiltrationFiltration and microfiltration are used to separate solids, particulates or large molecules from fluids (liquid or gases) in order to purify the filtrate. Explore a range of filter formats, including filter paper, plates and membranes for your separation needs. While larger particulates may be separated by gravity filtration, smaller particulates may require additional force for timely separation. Microfiltration equipment includes vacuum filters, as well as positive pressure, crossflow and centrifugal filtration devices.
