Title:   Quantitation of Cannabinoids in Cannabis Dried  Plant Materials and Concentrates Using Liquid  Chromatography‐Diode Array Detection Technique with  Optional Mass Spectrometric Detection  Author(s):  Lukas Vaclavik, Frantisek Benes, Ales  Krmela, Veronika Svobodova, Jana Hajslova and  Katerina Mastovska   ‐Submitted by: Katerina Mastovska, Eurofins  ‐Primary Reviewer:  Peter Indick, Microbac  ‐Secondary Reviewers:  Chris Hudalla, Proverde Labs 

Dissenter comments: 

 Step Fb4 is imprecise, I can see the possibility for changes  in solution volume that will throw off the accuracy of the  analysis.     Test samples where high in CBD and low in d9 THC. When  analyzing high THC samples, the large peak for d9 THC  will likely drown out the d8 THC peak. Which makes this  method less useful in real life conditions.  The ERP members discussed these comments with the method  authors and agreed that, while these may be valid points in  certain situations, they do not disqualify the method from  meeting the SMPR.    MOTION to move this method to First Action Official Methods  of Analysis Status (Audino/Reibach)   13 in favor, 0 opposed, 2 abstentions.  The motion passed.
