Abstract
= 0.9998, respectively), as well as comparable accuracy (-2.7 to 14%) and precision (RSD 1.7-11%). The method was further validated by the analysis of 10 commercial oils by Ag(I)-impregnated paper spray MS and UHPLC-UV analysis. Based on the determined relative concentration ratios of THC/CBD and the declared CBD concentration, 6 out of 10 CBD oils appear to contain more THC than the Dutch legal limit of 0.05%.
