A validated ultra‐high‐performance liquid chromatographic (UHPLC) method was used to determine the phenazepam dosage in clandestinely produced Erimin 5 tablets. Tablets from five different seizures submitted to the laboratory in 2013 were found to have a dosage of about 2.4 milligrams. The measurement uncertainty of the assay was estimated to be 3.2 % (relative) at a coverage factor of k=2. As an adjunct study the dyes in the tablets from several seizures were determined by thin‐layer chromatography (TLC) for future comparative studies.
