Potency Testing by (U)HPLC
HPLC Analysis
The Shimadzu Hemp Analyzer has been extended to include the analysis of 15 cannabinoids in 15 minutes. The
cannabinoid list is the same as on page 4 with the addition of CBDVA, THCVA, CBCA, and CBL. The method uses
Shimadzu’s 11-part cannabinoid mix (220-91239-21) plus the four individual standards. For the full application,
request Shimadzu’s Application News No. HPLC-036.

UHPLC Analysis
Shimadzu’s Nexera-i (LC-2040C 3D) UHPLC with a photodiode array (PDA) detector offers a solution to 16
cannabinoid analysis. The cannabinoid list is the same as on page 4 with the addition of CBNA, CBDVA, THCVA,
CBCA, and CBL. The method uses Shimadzu’s 11-part cannabinoid mix (220-91239-21) plus the five individual
standards. UV-Vis detectors provide the absorption at fixed wavelengths (i.e. 220 nm). The key advantage of the
PDA detector over a standard UV-Vis detector is that the full absorption profile from 190-400 nm is recorded. PDA
detectors are often used in the pharmaceutical industry to determine peak purity. For the full application, request
Shimadzu’s Application News No. HPLC-020.
